  • Patent number: 9012341
    Abstract: Continuous treadmill belt comprising a continuous first foamed layer (11, 12, 13, 14, 15, 16, 17, 18) made of thermoplastic foamed material, with an upper side (25, 26) and an under side (34, 35, 36), wherein a first pulling body (41, 42, 43, 44, 46, 47, 48) is arranged on the under side (34, 35, 36) and comprises a first textile layer and a pulling body under side (54, 56, 58), and wherein no layer is arranged between the continuous foamed first layer (11, 12, 13, 14, 15, 16, 17, 18) and the first pulling body (41, 42, 43, 44, 46, 47, 48), which hinders a local shearing displacement of the first pulling body (41, 42, 43, 44, 46, 47, 48) parallel to the under side (34, 35, 36) or stiffens said pulling body.
    Type: Grant

  • Patent number: 8544637
    Abstract: A continuous conveyor belt (1) has a transporting side and a driving side (31). Arranged on the driving side (31) are driving ribs (2), spaced evenly apart in the running direction (9) of the conveyor belt and running transversely to the running direction (9) of the conveyor belt. The driving ribs (2) have lateral guiding elements (21) for longitudinally guiding the conveyor belt (1) on teeth of a driving element. These lateral guiding elements (21) are formed in the manner of crests of a wave. This ensures good cleanability.

  • Patent number: 7824742
    Abstract: Conveyor belt bodies having a plastic material or having an upper plastic layer that typically has an elasticity module of between approximately 200 and approximately 900 N/mm2 , the bodies being coated by means of a plasma coating, especially in a plasma produced by microwaves or high frequency, whereby conveyor belts with covering layers are obtained. The covering layer provides the conveyor belts, for example, with increased chemical or scratch resistance or reduces the abrasion thereof. Suitable monomers for the plasma coating are, for example, tetrafluorethylene, 1, 2-difluorethylene, acetylene or hexamethyldisiloxane.
