Cutting and hemming system

DETAILED DESCRIPTION Referring now in more detail to the drawing, in which like numerals indicate like parts throughout the several views, FIG.
1 illustrates the cutting and hemming system 10 which includes first feed means 11 for pulling cloth 12 along its length from a supply such as reel 13.
Second feed means 15 also receives the cloth 12 and pulls the cloth along its length through first and second edge treating stations 16 and 17.
Third feed means 19 pulls the cloth from second feed means 15 into cutting station 20.
The cloth is then cut into sections 21 and moved at a right angle with respect to its first direction of movement through the second leg of a U-shaped path through a third edge treating station 22, the cloth is then turned through a right angle into the third leg of the U-shaped path where it passes through the fourth edge treating station 23, and the cloth is subsequently stacked at 24.
The first feed means 11 comprises a driven roller 25 and an idler roller 26 and the cloth 12 is fed between the rollers.
The cloth extends in a downward direction at 12a from feed means 11 through a loop 12b about the lower surface of loop control bar 28.
As is illustrated in FIG.
2, loop control bar 28 is hingedly mounted to the back surfaces of upright support posts 29 and 30 and its weight tends to cause it to rest in the loop 12b of the cloth.
Sprocket 31 rotates with loop control bar 28, and its chain 32 is connected to the sprocket 33 of variable speed transmission 34.
Electric motor 35 drives the input sprocket 36 by means of its sprocket 37 and chain 38 of variable speed transmission 34, and the output sprocket (not shown) and chain 39 drive the driven roll 25 of the first feed means 11.
When loop control bar 28 tilts in a downward direction because of an additional supply of cloth 12 in the loop 12b, its chain 32 will rotate the sprocket 33 in the variable speed transmission 34, causing the output chain 39 between the variable speed transmission 34 and the driven roller 35 to decrease in velocity, so that cloth is fed to the loop 12b at a slower rate
