The sample fabric weaving loom is designed for the preparation of short-length warps by pulling from a number of bobbins according to a single or warp color report. With the sample warp preparation process, it eliminates the creel system used in conical and serial (parallel) warp preparation and provides benefits for the warp preparation process in a smaller area.
The fabric sample to be produced is woven on the fabric design loom, that is, on the sample fabric loom, before mass production begins. In textile factories weaving fabric DRESSING or PATTERN There is a section.
The employees who have the qualification of designer working here are those who graduated from the Weaving Department of Vocational High Schools (current Textile Technology Field Weaving Designer Branch) and those who graduated from the faculties of universities that provide Textile Education. Those who place orders for fabric to be woven into the factory, that is, those who make their living by buying and selling fabrics, come and negotiate with the relevant department.
In this meeting, either they look at the fabric cards that the factory has produced and sold before, or they have a fabric sample in their hands and they want to have the same fabric or similar fabric woven by giving this fabric sample.
This sample is any fabric found in the Pattern section. DESIGNER It is shown to the customer by being analyzed by (weave, calculations, etc.) and weaving on the sample bench. The customer, on the other hand, orders the factory to weave this fabric according to this sample fabric. After that, in the weaving machine (it is woven on the loom)
At the same time, designers make fabric design (patterns and calculations and other details are prepared) and weave on the sample loom, that is, on the fabric design loom. The fabric coming out of this loom is called raw fabric. (Raw Fabric = HK in calculations.) It is shown to the customer.. If the customer wants, he places an order. This is why the template loom or fabric design loom must be used.
Fabric weaving factories always have to sell the fabrics they produce in order to survive. For this, from the samples of every fabric it produces. creates a CARTEX.
Rather, it has to be created. In this card, a code number is given to the fabric. When the customer comes, he looks at these cards and gives his order. Details of the code number of the fabric for which this order is received are available in the design section. With the cartexing system, huge time losses are minimized.
Warp lengths of sample weavings are shorter than mass production.
Sample fabric weaving machine is used extensively in the design units of weaving enterprises..
The sample fabric weaving machine is a tool made of wood or metal, used for weaving fabrics with a maximum width of 45 cm, used in transferring theoretical knowledge to practice and in weaving design studies, which can be 4 – 24 frames.
Due to the small number of short warps used for the sample fabric weaving machine, machines with high winding capacity are not required for warp preparation.
Sample warping machines are commercially available for use in such studies. Although it may seem like an advantage that sample warping machines do not require a creel system that takes up a lot of space, it is a disadvantage that such machines are offered for sale at high prices.
Since the relevant sector is important in design, it invests in sample warp preparation and sample fabric weaving machines.
In Sample Weaving Looms ie in Fabric Design Benches Warping Preparation
The most used method is warp preparation on rods attached to the wall.
The warp threads prepared in this method are obtained from a small number of bobbins, often even from a single bobbin.
The warp maker moves back and forth between the two leading and trailing rods attached to the wall as much as the warp wire required for the fabric.
The length of the distance between the two bars can be drawn in warp.
While this distance is sufficient in some applications, it may be short or long in some applications.
The distances of these wall-mounted bars cannot be changed most of the time.
For this reason, it is necessary to comply with the tool in determining the warp length. It is necessary to get help from at least one person in the warp preparation and transfer to the machine.
The warp prepared in such a mechanism makes the person who prepares it physically tired.
for example;
Considering that 4 warp wires will be drawn in the warp tool attached to the wall in the range of 180 meters, the warp maker must go back and forth between two bars of 180 X 4 = 720 meters in order to complete this warp.
In addition to this difficulty, warp preparation is a task that needs attention.
When the warp cannot be prepared properly or if the preparers make a mistake, the warp threads get mixed up and cause unnecessary consumption of weaving threads, which are hardly provided by educational institutions.
In addition, this situation brings with it the consumption of time and effort.
For this reason, automatic sample warp preparation machines are used in the preparation of the warp for weaving sample fabric in some enterprises.
Now, as an example, let's see what kind of preparations are made for weaving a warp Rips Knitted fabric on the SAMPLE WEAVING loom:
The texture formed by the plain weave by increasing in the warp direction is called the warp rips weave.
Let our example weave be a 2/2 Warp Rips weave.
According to the warp and weft color report of the fabric we will weave, we prepare our warp according to the warp and weft thread count and warp thread count.
In the preparation of the warp, it is necessary to pay attention to the warp color pattern and the crossing of the yarns respectively. If the warp color report is not the same as the warp color report of the sample we are going to weave, the unraveled warp is useless.
If maximum care is not taken in crossing the buttonholes, the order of the warp threads will not be clear and weaving will become difficult.
After the preparation of the warp is finished, the sample is wrapped on the warp beam in equal tension in the form of hanks or bands, passed through the warp bridge and passed through the cross laths without breaking the cross of the warp threads.
After that, drawing-in is done according to the order of the warp threads on the diagonal. Our knitting was 2/2 Warp rips knitting. 2 frames according to the drawing plan DUZ Yani SIRA we make a harvest. Here, we calculate the strength wire we need to put in each frame according to the number of warp wires, and according to that, we string the strength wire in each frame as needed.
While doing this will draw power or draw power (You can use it after you design a tool like this that will do this task and test the usability of the tool you designed.)
The person on the fabric beam side determines the frames according to the drawing-in plan and passes each warp thread through the power wire. The person on the warp beam side, on the other hand, extends it to the person who draws in according to the diagonal order of the warp threads. To the person on the warp beam side TAHAR RACKER as for the person who is on the fabric beam side TAHAR PIONEER It called.
What are impacted teeth?
When one or more teeth fails to grow in the correct position and is therefore held below the normal gum line, it is called an impaction. This can be complete, such as completely unerrupted (buried) third molars (wisdom teeth) or partial when just part of the tooth is visible in the mouth.
Why are impactions important?
For best function and appearance the teeth should grow in a healthy alignment. When one or more teeth is impacted, this can affect the function of that tooth but also the function and appearance of other teeth.
Whether all impactions should be treated is still controversial and your dentist and oral and maxillofacial team can explain the advantages and disadvantages or treatment for you, which is usually surgical.
Reed drawing is done for the warp threads, the strength of which is completed. (You can design a tool like this one to do this task and use it after testing the usability of the tool you designed.)
If the reed is to be passed through the tooth of the comb, it is taken in order according to the number, and the carding is completed. This process is done with the Card Drawer.
Warp threads that have been removed from the combIt is passed over the umaş bridge and connected to the fabric beam in hearts and with the same tension.
After these processes, the dobby of the pattern of the fabric whose sample will be woven is nailed to the dobby pallet.
The stoppers seen in black above are;
After the dobby movements of the pattern are nailed to the dobby pallets, these pallets are placed in the dobby assembly on the sample fabric loom.
After that, the weaving process begins. The weft bobbin, which will be used for weaving the sample fabric, is placed in the shuttle.
After that, the weaving process is done.
