Abstract
Specified is an extrusion profile of a thermoplastic material for transport or drive belts. The extrusion profile is reinforced in that a content of approximately 0.5 to 40 percent by weight of glass fibers, aramide fibers, or carbon fibers are mixed with the plastic. The extrusion profile can be welded into infinite belts with or without plastic casing.
Claims18
An extrusion profile of thermoplastic material for transport and drive belts, comprising:
- an extrusion having a cross-section profile, said extrusion comprised of a homogeneous mixture of an extrudable plastic and reinforcement fibers mixed with the plastic, said fibers comprising approximately 0.5 to 40 percent by weight of the mixture.
A method for producing an extrusion profile of thermoplastic material for transport or drive belts comprised of a mixture of an extrudable plastic and reinforcement fibers, comprising the steps of:
- providing a powdered or granulated plastic;
- providing staple fibers as the reinforcement fibers;
- mixing the plastic with the reinforcement fibers to produce a homogeneous mixture wherein the reinforcement fibers comprise approximately 0.5 to 40 percent by weight;
- extruding the mixture through a die adapted to produce an extrusion having a cross-section profile.
