Description

The device for measuring the width of the fabric consists of two measuring rollers, between which the measured fabric is passed, and differs from limestone in that one of the rollers is made in the form of two drums, enclosed in one another, while the outer drum, rotated by the moving fabric, has both ends forming a series of holes through which spring loaded puffs protrude.

When in contact with a passing fabric, the pins settle under a special latch and act on the protrusions of the inner drum, which are located spirally but its surface. In accordance with the number of recessed pins of the outer drum and due to their alternate engagement with the protrusions of the inner drum, the latter rotates through one or another angle, which characterizes the width of the passing fabric in digital 1;

FIG. 1 shows a front view of the device; in fig. 2 - its side view.

The measuring rollers 1 and 2 are connected by gears 3 and thus have the same peripheral speed. Spring 4 roller 2 when 10

squeezes roller. The roller 1 at both ends along the generatrix has a series of holes 5 located under the respective spring-loaded pin 6. In their upper position, the pins 6 are fixed by balls with springs 7, as shown in Fig. 2. The pins 6 extend into the holes 5 and expose the surface of the roller /. Inside the roller / there is a shaft 8 on which drums 9 and 10 are rigidly mounted at both ends. At the protruding end of the shaft 8 there is a gear 11c with a pawl 12, a digital wheel 13 and a spring 14 that holds the shaft and drums from rotating,

The drums 9 and 10 have, on their surface, protrusions 15, which are arranged spirally to their surfaces.

During the rotation of the rollers 1 and 2, the pins under the influence of the alkali passage below them, the tissues are inserted inside the roller /; engaging the protrusions 15, they rotate the drums until they fall under the turn-off support 16, which leads to the initial position and thereby remove the roller / and drums 9 and 10 from the engagement. The roller continues to rotate and the drums 9 and 10 of the shaft 8 stop and po147

The return of the drums 9 and 10 to the initial position is carried out by the spring 14 when exposed to a special hole, Pa, the tail pawl 12.

Prede invented and

A device for measuring the width of a cloth, consisting of two measuring shafts, between which the measured tissue is passed, characterized in that one of the rollers is made in the form of two prisoners, one inside the other drums, of which the inner one is rigidly fixed on

the rotation of the clockwork li is equipped with spirals arranged at equal distances in two spirals, and the outer, freely carried by the moving fabric, has a number of openings along the generatrix with spring-loaded pins protruding under the latch with the moving fabric to In accordance with the number of recessed pins, the axis of the first roller rotated at one or the other angle, as a result of alternately coupling the outermost of the pins flooded inside the drum with the corresponding Lugs the inner drum.
