Abstract
A module for chains or belts that is molded from a plastic compound containing a magnetizable element. The molding may be performed in a standard injection molding machine equipped with a device that produces an electromagnetic or permanent magnetic field. The field lines are directed in such a way as to penetrate the mold cavities and the molded part in the desired axis, in order to electrically charge the magnetizable particles and orient them to form a permanently magnetized plastic body. After discharge of the mold, the plastic part has magnetic properties with opposite charges at opposite poles.
Claims8
A modular chain apparatus, comprising:
- a track having a U-shaped channel formed by an intermediate section connected to a pair of side walls, the track having a magnetic element disposed therein;
- and
- a chain module having a conveying surface, a first hinge eye disposed at a first end of the chain module and a pair of spaced apart second hinge eyes disposed at a second end disposed opposite from the first end, the chain module molded from a composition having a magnetizable material with magnetizable particles capable of forming a permanently magnetized chain module when exposed to a magnetic field during molding.
A modular belt system, comprising:
- a modular belt having a plurality of belt modules, each belt module having an intermediate section with a first plurality of link ends extending in a first direction therefrom and a second plurality of link ends extending in a second direction opposite the first direction, the first and second plurality of link ends having transverse openings defined therein, the transverse openings on the first and second link ends capable of aligning when the first link ends are intercalated with the second link ends of an adjacent module, the belt modules capable of being pivotally connected in rows by a pivot rod, at least one module molded from a composition having a magnetizable material with magnetizable particles capable of forming at least one permanently magnetized belt module when exposed to a magnetic field during molding;
- and,
- at least one support strip having a magnet disposed thereon.
