  • Patent number: 6581758
    Abstract: A conveyor mat comprises a number of plastic modules succeeding each other in a conveying direction and whose top sides form a conveying face and provided with converging hinge loops which have equal basic forms and which alternately extend forwards and rearwards relative to the conveying direction and successive modules are coupled by means of hinge pins, such that the forwardly extending hinge loops of the rearmost module can slide between the rearwardly extending hinge loops of the next module between a slide-out position and a slide-in position, a sidewall of a forwardly extending hinge loop is provided with a projection which in the slide-out position cooperates with the top of the adjacent, rearwardly extending hinge loop, and the sidewall of the adjacent hinge loop is provided with a recess in which the projection can be received during sliding into the slide-in position.

  • Patent number: 6227356
    Abstract: A conveyor mat for conveying products in a conveying direction between at least two divert wheels. The conveyor mat comprises a number of rows of side-by-side modules succeeding each other in the conveying direction and extending transversely to the conveying direction. Incorporated into the conveyor mat are a number of guide modules which have their bottom side provided with guide members for cooperation with a guide provided on a conveying track. According to the invention, the guide modules are incorporated into the conveyor mat so as to be substantially equally spaced from one of the lateral edges thereof, such that the guide members together constitute one narrow, slotted guide track extending in conveying direction. In an advantageous manner, the guide modules can be incorporated adjacent a lateral edge of the conveyor mat or in or adjacent the center of the conveyor mat.
