SU818474A3 - Method of laying thread-like material into rotating cylindrical basin - Google Patents

Abstract

Fibre tows are laid in spinning cans along paths which extend from the radially outer point of the can towards the centre of the can and back to the point, whilst the point of reversal of the path is disposed on a circle concentric with the longitudinal axis of the can. Acceleration and deceleration peaks are reduced and the tows are laid into cans at more uniform rates.

Description

one

The invention relates to the textile industry, in particular to methods for laying filamentary material, for example, a fibrous tape.

There is a method of laying a filamentary material into a rotating cylinder. a pelvis by moving the material through a spreading device, which is reported in the cross section of the pelvis to reciprocate at an alternating speed and reversing near the pelvic walls in places located on opposite sides of the diametrical plane of the pelvis f.

However, this method does not allow high-quality stacking of the material due to its accumulation in the Center of the stasis due to the movement of the spreader through the center of the pelvis.

The purpose of the invention is to improve the quality of styling.

This goal is achieved by moving the picker along a path that is offset from the pelvis axis, and the speed of the picker is changed in inverse proportion to its distance from the pelvis axis. In this case, the spreader is moved along an arcuate trajectory or along a trajectory that represents two intersecting arcuate lines placed specularly about the diameter of the pelvis. In addition, the specified distributor is moved in one direction with an average speed different from the average speed of movement in another direction.

10 FIG. 1 shows the location of the material in the pelvis after it is laid; in fig. 2-5 options for laying material.

Stacked filament material

5 1 representing, for example, a thread, is guided through a clapper (not shown), which is moved in a cross section of the cylindrical pelvis 2 along a rectilinear trajectory 3 return 20 retransmittingly reversing near the pelvic steiok in places located on opposite sides of any diametral plane intersecting the trajectory 3.

25 The trajectory 3 of movement of the handler is shifted relative to the axis 4 of the pelvis 2 by the radius of the circle 5 and is located tangentially to this circle. The pelvis is rotated clockwise or

30 counterclockwise. Spreader

is moved along a variable speed trajectory 3, which is inversely proportional to the distance of the spreader from the pelvis axis. The speed of the handler reaches its highest value when it approaches the axis of the pelvis, and near the walls of the pelvis, it decreases to zero. Due to the rotation of the pelvis and the linear movement of the spreading device, the thread in the form of coils is placed in the pelvis, while the coils slide into the pelvic center area bounded by a circle 5 and fill this zone (Fig. 1), thereby preventing the pile up in the pelvic center.

When the clapper moves from left to right, it moves against the direction of rotation of the pelvis, and when the follower moves backward, its direction coincides with the direction of rotation of the pelvis. As a result, there is a difference in the speeds of movement of the point of the thread in its two adjacent turns. To eliminate this, the average speed of movement of the handler and, accordingly, the thread increase and move it from left to right.

It is possible to move the spreader along an arcuate trajectory b (Fig. 3), the extreme points of which are not located on the diameter of the pelvis. Such a spreader movement is easier to implement.

In the variant of the spreading device movement along the arcuate trajectory 7 (fig. Its reversal points are located on the diameter of the pelvis, and the height of the arc is equal to the shortest distance to the pelvic axis

The movement of the handler along the path in the form of two arcuate lines 8 and 9 intersecting the pelvic walls, which are mirrored relative to the diameter of the pelvis, eliminates the need to introduce the difference in the average motion speed of the handler in both directions, as in both cases it moves against the direction of rotation of the pelvis (Fig. 5).

This method allows you to eliminate the accumulation of the thread in the center of the pelvis and, therefore, to improve the quality of its strings. Ladki.
