Abstract
The present invention relates to a jointing press for jointing a first and second free end of one or more belts which is adapted to raise directly the temperature of the surface of the belt (or belts) thereby decreasing heat-up times and which exploits the unheated platens to act as a heat sink in the cooling step thereby eliminating the need for external water or forced air cooling sources.
Claims21
A jointing press for jointing a first free end and a second free end of a belt (or belts), said jointing press comprising:
- a fist and second supporting means each supporting a platen so as to expose a pressing surface thereof and a heating element adjacent to and substantially thermally insulated from said pressing surface;
- a contact coating applied to said heating element of each of said first and second supporting means, wherein in use the first supporting means and second supporting means are stacked whereby to capture between the contact coating applied to the heating element of the first supporting means and the contact coating applied to the heating element of the second supporting means a surface of a belt (or belts) defining the first and second free end of the belt (or belts);
- and
- an urging means for progressively urging together the pressing surface of the platen supported by the first supporting means and the pressing surface of the platen supported by the second supporting means whereby to apply pressure to the surface of the belt (or belts) defining the first and second free end of the belt (or belts).
A jointing press as claimed in any preceding claim wherein each of the first and second supporting means adopts a box-like configuration for housing the body of the platen in such a manner as to expose the pressing surface thereof.
A jointing press as claimed in any preceding claim wherein each of the first and second supporting means is a carbon fibre shell.
A jointing press as claimed in any preceding claim wherein the heating element is substantially thermally insulated from said pressing surface by an insulating filler.
A jointing press as claimed in any preceding claim wherein the urging means is pneumatically driven.
A jointing press as claimed in any preceding claim wherein to the first supporting means is secured one or two supporting lips for bearing at least a part of the surface of the belt (or belts) defining the first and second free end of the belt (or belts).
A jointing press as claimed in any preceding claim wherein in use the first supporting means and second supporting means are stacked with the contact coating applied to the heating element of the first supporting means facing the contact coating applied to the heating element of the second supporting means and with the surface of a belt (or belts) defining the first and second free end of the belt (or belts) therebetween.
A jointing press as claimed in any preceding claim wherein one or more clamping devices are mounted on the first and second supporting means to withstand any tendency for the contact coatings to diverge.
A jointing press as claimed in any preceding claim wherein the contact coating is composed at least partially of TEFLON®.
