ABSTRACT:
A module for forming a conveyor belt (22) having a high friction conveying surface and which is comprised of a plurality of identical modules (36, 38, 40, 42 and 44) preferably formed by injection molding is disclosed. Each module (36) has a top portion and bottom portion, and includes a plurality of elongated elements each of which has first pivot ends (36A) and second pivot ends (36B) formed integral with an intermediate section (54). Each of the plurality of pivot ends define pivot holes (62) which have axes (64 and 66) aligned such that the pivot ends of other modules may be pivotally connected by a pivot rod (46 and 50). Modules of a conveying belt include a device for receiving a driving force which is applied to the module orthogonally to the pivot axis and substantially parallel to a first plane defined by the first and second axis (64 and 66). The top side of each module defines an area (74) for attaching a frictional member (72 ) and the frictional member (72) has a bottom side or attaching portion (80) which cooperates with the area (74) on the top side of the module. Each frictional member further has a top side (78) which forms the conveying surface of the conveying belt (22) such that the conveying belt (22) will exhibit increased friction characteristics and thereby reduce slippage between the conveying belt (22) comprised of the modules and items (28 and 30) conveyed by the belt.
