Abstract
The deformable driving band (3) or similar comprises passage means (2) passing through the band and opening out, towards the inside, at right angles to pockets (5) or similar provided in a compressible strip (6) extending over the whole driving band, the assembly being such that a suction phenomenon increasing grip is created by the compressible strip (6) and the packets (5) in deformation zone of the driving band (3) corresponding to an expansion phase of said pockets (5).
Claims13
A non slip system for a deformable driving band having a bearing surface comprising passage means passing through the driving band, said passage means comrising channels having an outer open end at said bearing surface, said channels being slanted with respect to a direction perpendicular to said bearing surface, each channel comprising two channel parts having concave sides turned towards each other, said two channel parts being provided in two transverse blocks of material separated by a slit, said slit providing sealing of the blocks during crushing of the driving band, and moving slightly away from each other during decompression of the band.
