## Abstract

A method for producing fabric reinforced tapes of vulcanizable rubbery material, to be wound and stocked in bobbins, comprising progressing the formed tape under means adapted for applying a thin layer of anti-adhesive zinc stearate on one face of the tape, preparatory to winding the tape into bobbins the turns of which are to be prevented from sticking to each other.

## Claims

### Claim 1

A method, for the formation of a tape having raw vulcanizable rubber exposed at one major face of the tape and fabric exposed at the other major face of the tape, which comprises the steps of:
(i) entraining the tape about successive spaced guide rollers such that the portion of tape lying between the rollers is substantially horizontal and has said one major face of raw vulcanisable rubber exposed upwardly;
(ii) depositing downwardly onto said upwardly exposed substantially horizontal major face of said tape portion a layer of zinc stearate powder to provide a powder-bearing face on which some of said powder is secured by tackiness of the rubber to serve as an anti-adherent, whereas other of said powder remains loose on said upwardly exposed face;
(iii) causing said tape as it leaves the downstream one of said guide rollers to have a portion of its length passing upwardly at an inclination, and
(iv) acting with a rotary brush, disposed at an intermediate position along the upwardly inclined portion of tape, on said powder-bearing face for removing from said face that powder which remains loose on said face.

### Claim 2 (depends on 1)

The method claimed in claim 1, including the further step of thereafter dividing said powdered brushed tape longitudinally into plural tape portions.

### Claim 3 (depends on 2)

The method claimed in claim 2, including the further step of winding each of said plural tape portions individually into a respective bobbin of tape.
