P.63. In flat knitting machines with a single system, the slideway, that is, the machine width How is (cm) calculated?
C.63. Slideway (machine width) (cm) = Machine Working Width (cm) + ( 2 x Return path (cm) (sum of parts not worked on the machine)
P.64. How is the machine speed ((m/sec.) calculated on flat knitting machines with a single system?
C.64.Machine speed ((m/s.) = Slideway (machine width) (cm) x Number of round trips per minute (course/min.) / 100
P.65.The working width of the single-system flat knitting (knitwear) machine is 320, the return path is 40 cm, and the machine speed is 16 rpm. What is the working speed of this machine?
C.65. Machine speed ((m/s.) = Guideway (machine width) (cm) x Number of round trips made by the machine in one minute (stroke/min.)
Machine Speed (m/sec.) = Slideway (machine width) (cm) xn(stroke/min. /100 x 60
Slideway (machine width) (cm) = 320 + (40x2) = 400 cm
Since the sled covers the return path once on the way and on the way back, the return path is multiplied by two when calculating the width of the machine.
Number of round trips made by the machine in one minute = 16 (rpm) x 2 = 32 strokes/min.
Machine speed (m/s) = 400 x 32 / 100 x 60
Machine speed (m/sec.) = 2.13 m/sec.

P.67. How to find the number of rows (course/min.) on multi-system machines?
C.67. In multi-system machines, the number of revolutions is multiplied by the number of systems, and the number of rows per minute (course/min.) is found.
P.68. In the six (6) system flat knitting (knitwear) machine, the working width is 320, the return path is 40 cm, and the machine speed is 16 rpm. What is the working speed of this machine?
C.68.
Machine speed ((m/s.) = Guideway (machine width) (cm) x Number of round trips made by the machine in one minute (stroke/min.)
Machine Speed (m/sec.) = Slideway (machine width) (cm) xn(stroke/min. /100 x 60
Slideway (machine width) (cm) = 320 + (40x2) = 400 cm
Since the sled covers the return path once on the way and on the way back, the return path is multiplied by two when calculating the width of the machine. In machines with more than one system, the number of revolutions is multiplied by the number of systems.
Number of round trips made by the machine in one minute = 16 (rev/min.) x 2 = 32 courses/min (for a single system) 32x6= 192 courses/min. ( for 6 systems )
Machine speed (m/s) = 400 x 192 / 100 x 60
Machine speed (m/sec.) = 12,8 m/sec.
