TYPES OF TEMPLES (SIDE ROLLER)

Side roller temple :-

The side roller temples are fitted in a cast iron case and mounted at each side of a fabric upon a rod a shown at fig. 193

Fig. 193 side roller temple:-

 The rod may be provided with holes for two studs B to pass through . The stud B are bolted on the breast beam . Each stud has a special spring over it to hold the temple forward, and a nut C is  secure A upon B. or flat S-shaped spring may take place of spiral springs. 

For ilght goods the rollers D may be of best quality wood with steel journals and steel hooped at one end , but solid brass and steel and brass- covered roller often used. In each case finely pointed steel pins are driven into the rollers specially. Soft steel from 3"to 6" or 7.62 cms. to 15.24 cms. long by 1/2" or 1.27 cms. diameter is also employed. The body of each roller contains a large number of short sharp point which leans towards the selvedge of a cloth. Some rollers are slightly conical in form , the taper being formed 3/4" to 7/8" or 1.9 cms. to 2.2 cms. in diameter on a 4" or 10.16cms. roller.

A temple case is open below to allow size and direct to fall out. A moveable cap is screwed down tight , but a space is left facing the roller axis for a fabrics to enter , as the latter is drawn forward: it is bent over the roller points and held by them sufficient velocity to ensure good weavning.

USES:-

(a) The side roller temples are specially suitable to hold out light fabrics and are also on medium and moderately heavy looms in which the sley moves very near to the breast beam and leaves no sufficient space for more than one roller .

(b) In colored cotton weaving double-roller temples are largely used. The rollers are 3.25 to 6" or 8.25 cm. to 15.24 cm. long and from 7/8" to 11/16" or 2.2 cm. to 1.75 cm. in diameter. They are placed on pairs near each selvedge of a fabrics . Both may be uniformed in size or conical . Spiral springs short horizontal and long vertical flat springs, are used to hold the temples forward to permit them to move backward when a shuttle strikes them.

(c) If properly constructed, the side roller temple is simpler and more effective than any other temple is applicable to wide range of fabrics, particularly cotton fabrics. Three rollers are sometimes used in placed of two rollers. The teeth in that case, should be as short as possible or the cloth will not be freely liberated and 'temple marks' will be visible.

(d) Many temples are capable of preventing a fabric from contracting unduly, but are distend it. In other words, the temples may prevent contraction but cannot stretch it.
