Description

 The outer planes are installed on the macani zone, which is limited to the direction of the forms of the side walls of the subcell, with the possibility of reciprocating movement in the vertical plane.

The drawing shows the proposed bath.

The bath 1 for making blanks of blanks has a jacket 2, which is filled with water to maintain the latex working temperature, the pan 3 and the stirrers 4, 5 opposite each other. Respectively, in the gaps a and b between the side machines of the bath 1 and the side walls of the pallet 3, which limit the macani zone in the direction of the mold movement. On the side walls of the pallet 3 there are fastened straps 6 installed with the possibility of reciprocating movement in the vertical plane. In the upper part of the bath, there are mounted guides 7 for moving mold holders 8 with shapes from position A to position B and a device for moving molds, made in the form of rotating closed chains 9 with retainers 10 fixed to the links.

Bath works as follows.

The bath 1 is filled with liquid latex to a predetermined level, the rotation of the mixers 4 and 5 is turned on, and the bars 6 are set so that the speed of the surface latex layer over the bath mirror is equal to the speed of movement of the forms.

At position A, using a reloader (not shown) vertically, the form holder 8 is lowered down with the molds on direction 7. The stops 10 fixed on the closed circuit 9 move the form holder 8 with the forms along the guides 7 of bath 1 to position B. a layer of latex on the form. At position B, with the help of an overrider, the form carrier 8 with the forms is lifted vertically upwards and transferred to the next operation. The directional uniform motion of the surface layer of the latex is provided by the mixers 4 and 5, and the speed of the surface layer of the latex, equal to the speed of the mold holders 8 with the forms, is provided by the position of the strips 6, which creates favorable UEL for the formation of a quality film.

As the size of the molds changes, the volume of the extruded latex changes. and the thickness b of its surface layer, which leads to a change in the velocity of the latter.

To obtain high quality top-quality products at a certain

"The optimum rotational speed of the agitators, chosen experimentally before the start of the production of a commercial batch of products, the latex flow rate is regulated by means of vertical holes 6, which lift up

5 and thereby reduce the value (G, and to decrease the speed, the strips are lowered, increasing the thickness. 6 of the surface latex layer.

0 / Uniform movement of the surface layer of the latex prevents the formation of separate foci of coagulation on the surface of the latex /, which positively affects the quality of the product. The same speed of the surface layer of latex and forms provide a uniform build-up of latex over the entire circumference of the form. In addition, the elimination of coagulation foci on the latex surface excludes the operation of manual removal of the specified formations from the latex surface, which improves the performance of the bath.
