The invention relates to equipment)

for the processing of polymeric materials and can be used in the rubber industry, in particular on roller machines to improve their performance and the quality of the finished product.

The purpose of the invention is to improve the quality of the sheet materials obtained by uniformly distributing the material along the roll gap.

FIG. 1. shows the wedge fixture, general view; figure 2 - the wedge, in the case of the Central loading of the material ;, on fig.Z - the wedge, in the case of the end loading of the material; Fig. 4 shows a wedge with a loading area in the form of intersecting conical surfaces; Fig. 5 illustrates the distribution of the material supply along the roll with and without the present invention.

The wedge tool for roller machines for processing polymeric materials contains a wedge 1 mounted on the base 2 of the roller machine and entering with its trust 3 in the gap between the rolls 4 and 5 (figure 1). The side working surface of the wedge 1 has an upper loading zone 6, made in the form of two inclined sections -. stacks located at an angle to one another, the intersection line 7 of which belongs to the transverse plane of symmetry of the wedge 1, and the lower deforming zone 8 corresponding to the cylindrical surface of the rolls.

The inclined sections are formed by planes bounded by contours in the form of truncated trapeziums, with a combination of like bases. The free base 9 of each trapezium, belonging to the end of the 10 wedge 1, is equal to the material

in the middle of the rolls- (FIG. 2) each free base 9 of the trapezium belonging to the end 10 of the wedge 1 cuts off

1, cuts off on the intersection line the post-gg of the additional working gap. The miniature base of the wedge base 12, the segment 1 is no longer than 8 magnitudes, the intervalal and maximum values, respectively, of the angle oL and segment 1, are limited by the size of the active deformation zone along the edge of the wedge, the circumferential edge.

gap q, counting from the same

In the case of material loading along the edges of the rolls (FIG. 3), the sizes of the cut-off sections I, and 1. will be respectively no more than 8 and 10-30

values of the roll gap q.

In another embodiment of the loading zone 6 (FIG. 4) of the wedge 1, the inclined sections can be made

in the form of conical surfaces with bases in the form of circles inscribed in the end planes 10 of the wedge, having inclined rotation axes and intersecting circumferentially touching the side working surface 8 and the base 12 of the wedge.

The wedge devices with loading zones 6 according to FIGS. 2 and 3 are simple to perform and contribute to

the rapid movement of the stock of material along the working gap between the rollers 4 and 5. The wedge device with the loading zone 6 according to FIG. 4 is more difficult to perform, but

effectively engages the material supply in the adjustment process due to the smooth shape of the loading zone 6,. ; appropriate form of stock material.

The device works as follows.

Before starting the wedge 1 is exposed parallel to the axis of the rolls 4 and 5, the polymer material is loaded,

for example (figure 2), in the Central part of the roll before entering the additional working gap. Due to the rotation of the work roll 5, the material is partially distributed over its surface, and

partially remains in stock at the entrance to the gap between click 1 and roller 5, However, due to the presence of inclined sections on the side working surface of the wedge 1, the stock of material moves towards a larger gap, i.e. in this case, along the rolls to their ends 10, ensuring its uniform flow into the roll gap. For preferred option

The segment 1 and the maximum values of the angle and the segment 1 are limited by the requirement to ensure a uniform distribution of the material supply along the house and the maximum values, respectively, of the angle oL and the segment 1, limited by the size of the active deformation zone along the edge of the wedge;

homogeneity of the properties of the semi-series.

It is four values of the roll gap, angle - 45.
