Temple Rollers.
The cloth as it is woven tends to contract in width in consequence of the tension at which it is wrought lengthway, and to counteract this, temple rollers are used. For commoner heavy fabrics the roller and trough is used, and consists of a fluted roller cut in the manner of a screw at either end, one end with left-hand thread and the opposite end a right-hand. Thus a spiral row of points is left at each end of the roller, and it is fixed in the loom, so that as the roller revolves the points distend the cloth. The roller is fixed in a trough for convenience in attaching to framework. Lighter fabrics are woven with side temples. These are small rollers acting only for a distance of 3 to 4 inches at the selvages of the cloth. Two pairs are usually used at each side, the contrary-thread spiral arrangement being preserved; a bar of iron connects the two sides. In the latter arrangement the weaver can see the cloth from the moment it is woven, which is not possible with the roller and trough, as some two inches are hidden under the roller: the cloth is not held so firmly at the middle of its width.
