Description

A device is proposed for drawing diagrams of changes in the width of the fabric on rejection machines and the like using known moving probes and a mixed paper tape for applying a measure of length and width. In this device, the probes are hinged on spring-mounted tires. The last system of strips and levers articulated with a writing device. In the drawing, FIG. 1 shows a top view of a device mounted on a scraping machine; FIG. 2 is a side view and FIG. 3-view (in two projections) of clamps of graphite sticks for applying curves.

Under the upper plank of the machine 1 on hinges 2, wood tires 3 and 4 are reinforced so that the distance between hinges 2 and studs 5 at one end of the tires is one tenth from hinges 2 to the roller probe: 6 at the other end tires .. The brad 5 is worn loosely on the ends of the slats 7 and 8, which are articulated with their other ends

Ш;

with the ends of the levers 9 and 10 rotating on the pins 11. The levers 9, 10 are hingedly attached two interlocking plates 12 with the hinges 13 and screws 14 for clamping the writing device (graphite) 15.

From the main axis 16 of rotation of the machine, the transfer system 17 goes to the roller 18, over which passes a perforated checkered paper tape 19, unwound from the roll 20. The transfer from the axis 16 to the roller 18 is taken at a rate of 1: 100 relative to the roller 21 moving the measured the cloth.

The device operates as follows. Having tucked the end of the paper tape under the writing device (graphite) 15 and passing the end of the cloth between the shafts 21, 22, the roller plow 1 6 is pushed aside and the machine motor is allowed to go. According to how many meters of fabric will move the shaft 21, so many centimeters of paper tape there is no roller 18, and graphite 15, under the influence of the spring 23, draws longitudinal curves on the paper. The width of the fabric is measured by the fact that

The loose probes 6 are in contact with the edges of matter, under the influence of the spring 24, retract the ends of the tires 3, 4 during the expansion of matter and constrict them when it is narrowed. Thus, the tires 3 and 4 by means of the plank and 8 and the levers 9 and 10 constrict and expand the recording lines on the paper tape. In this way, a paper photograph is obtained like a photograph of a drawn piece of fabric, and by its scale one can see its size both in length and in width, taking into account all width irregularities.

Prilmet invention.

A device for drawing diagrams of variation of the width of the fabric on rejection machines and the like, equipped with movable rods and tape for applying a measure of length and width, characterized in that the probes 6 are hingedly mounted on tires S and 4, spring-loaded 24 and articulated by a system of strips and levers with pisush, their gadget 15.
