Abstract:
1. An assembly of a guide bend and a modular conveyor chain, said guide bend including a segment comprising a profile from plastic material with a substantially flat upper side extending along an axis proceeding in a curved manner, with a guide face in which at least one guide is formed for guiding the modules of a modular conveyor chain, in which profile, adjacent the guide, magnets are included for pulling body parts of successive modules of the chain to be guided against the upper side through cooperation with hinge pins of the modular conveyor chain, wherein the at least one guide comprises two grooves proceeding in the longitudinal direction of the profile, so that, adjacent the guide face at the location of the guide, the profile has a substantially E-shaped cross section with a central projection located between the grooves and legs located outside the grooves on an inside bend side and an outside bend side of the projection, respectively, and that in the legs, magnets are included, and said modular conveyor chain comprising a series of successive modules from plastic material which are hingedly coupled with the aid of hinge pins from magnetizable material, and of which modules each is provided with a sheet-shaped body part with a conveying face located at an upper side of the body part, with hinge holes included in the sheet of the body part between upper and under side and with two projections provided at an underside of the body part, wherein sliding faces located at sides facing each other of the projections together with a sliding face located between the projections at the underside of the body part, form a longitudinal guide with substantially U-shaped cross-section, and wherein the projections are provided at a distance from the sides of the body part, and wherein adjacent the projections, at the underside of the body part, sliding surfaces are located which, with sliding faces located on sides facing away from each other of the projections, each form a longitudinal guide with substantially L-shaped cross-section, and wherein the hinge pins extend substantially over the width of the modules.
