Abstract
A process for welding profiles (1) of a thermoplastic or thermoplastic elastomer to a top layer (3) of a belt (2), such as a conveyor belt, also being made of a thermoplastic or thermoplastic elastomer. The process uses thermal impulse welding and applies the welding heat onto the surface (21) of the belt (2) which is opposite to the top layer (3). The process is in particular suited for welding TPO profiles to TPO top layers.
Claims14
A process for welding a profile (1) to a belt (2) comprising a top layer (3) with a top layer surface (31) and an opposing surface (21) opposite to the top layer surface (31), wherein the profile (1) comprises a first thermoplastic or first thermoplastic elastomer, the top layer (3) comprises a second thermoplastic or second thermoplastic elastomer, and the profile (1) is welded to a first location (311) on the top layer surface (31) using heat and pressure, characterised in that i) the welding heat is applied by thermal impulse heating;
- and ii) the thermal impulse heating is applied to a second location (211) on the opposing surface (21) which is opposite to the first location (311).
