Five wheel take-up motion ( a secondary loom motion)
Take up motion is a secondary loom motion. The take-up motion helps to perform continuous weaving of fabric. When the fabric is woven on the loom during weaving, it is pulled ( drawn) regularly according to picks per inch in the fabric. This fabric pulling ( drawing) process continues during loom operation. This drawn cloth is wound on the cloth beam or cloth roller).
In shuttle loom, intermittent take up motion is used. Actually, there are two kinds of take-up motions used in the loom.
1- Intermittent take-up motion
2 - Continues take-up motion.
Intermittent take-up motion
In this kind of mechanism, the emery roller does not rotate continuously. When the last inserted pick gets beaten by reed, the take-up roller draws the fabric in a forwarding direction and winds in on the cloth beam. The fabric pulling ( drawing) takes place intermittently.
There are two types of mechanisms used in shuttle loom:
1 - Five wheel take-up motion
2 - Seven wheel take-up motion
Five wheels take up motion:
I - fulcrum
G - pushing pawl
E - ratchet wheel
F - change pinion
A - beam wheel
B - pin roller or take-up roller or emery roller
H - catcher
C - stud wheel
D - stud pinion
J - finger
