EQUIPMENT FOR REPAIR AND JOINTING OF CONVEYOR BELTS

摘要

A belt press is formed of a longitudinal row of upright and abutting press frames each comprising upper and lower traverses respectively having lower and upper traverse faces and two upright tie bolts extending vertically between the upper and lower traverses and securing the lower traverse to the upper traverse. Upper and lower press platens carried on and between the traverses have respective upper and lower platen faces respectively confronting the lower and upper traverse faces. A belt workpiece to be joined or repaired is engaged between the platens. Respective upper and lower pressure plates engaged between the platen faces and the respective traverse faces have respective upper and lower heaters. Hydraulic actuators engaged between the upper traverse and the upper pressure plate are vertically expansible for displacing the upper pressure plate down and thereby pressing the platens against a belt engaged therebetween. The upper pressure plate is of U-section and upwardly open with a base lying on the upper pressure plate and a pair of sides projecting upward therefrom. The hydraulic actuators are between the pressure-plate sides and are constituted as at least one diametrally compressible but circumferentially unstretchable hydraulic hose forming a substantially closed chamber and lying between the pressure-plate sides.
