SU762997A1 - Device for impregnating fibrous material - Google Patents

Description

The invention relates to the processing of polymeric materials and can be used in the manufacture, for example, fiberglass. five

A device for the impregnation of a continuous fibrous material, containing an impregnating bath with orienting elements for displacing air from the interfiber space, θ v £ 11, is known. · ·. ·

However, to obtain a uniform high-quality impregnation is necessary,

that the harnesses enter the impregnation bath in the same loosened state; This device does not provide this.

Closest to the invention is a device for impregnating a fibrous material, containing 20 loosening chamber and installed on it in the course of the technological process (impregnation bath £ 2).

However, in this device the thread passes in the impact zone in the unstressed 25 state, as a result of which the effectiveness of the loosening device is low. The mutual orientation of the threads and impact elements cannot cause effective loosening of the material. In addition, to obtain high-quality material (especially for electrical purposes), the fiber must also be dried before impregnation.

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

This goal is achieved by the fact that in the device for impregnation of fibrous material containing a loosening chamber and an impregnation bath installed behind it during the process, the loosening chamber is made in the form of air ducts installed on both sides of the material being moved between two pairs of drive contacting shafts with an elastic coating which the device is equipped with.

The drawing shows schematically the device, a general view.

The device consists of a loosening chamber 1, made in the form of ducts 2 and 3, two pairs of shafts 4 and 5 with an elastic coating b and an impregnation bath 7. The bath contains the lower 8 and upper 9 blocks of orienting elements (knives).

The device works as follows. in a way.

Continuous fibrous material, for example stekloklaguty with creel, pass between the first pair of shafts 4,5a and then through the second pair. The shafts rotate synchronously from an external water pri- ^1, wherein they provide a sagging condition harness portion located between valami.Podavaemy via ducts 2 and 3 hot,
