An apparatus produces a tubular structure having a longitudinal axis and at least one form extending helically inward from the structure relative to the longitudinal axis. The apparatus includes an extruder including at least two spaced apart extrusion die surfaces adapted to extrude plastic state material therethrough. At least one extrusion die has at least one nonplanar channel having facing nonplanar surfaces configured and disposed such that during extrusion of the material through the at least one extrusion die, material flowing into the channel creates the at least one form. The channel surfaces direct material flow such that the at least one form and the structure exiting the extruder and last contacted by the at least one die of the extruder collectively helically rotate about the longitudinal axis.

Apparatus for producing a tubular structure

An extruded multiwall tubular structure formed from extrusion dies, the structure includes a core having a longitudinal axis and a first wall surrounding the core. At least one form extends helically relative to the longitudinal axis and between the core and the outer wall in supporting relationship therewith. At least the first wall and the at least one form lack residual strains, as a result of stress created by the manufacturing process, subsequent the structure exiting the extrusion dies. The core is concentric with the first wall.

Extruded multiwall tubular structure

A bridge for a conveyor system includes a bridge frame including a top support surface segment having a top support surface. The bridge frame further has first and second side walls extending downwardly away from the top support surface segment. Each side wall has a portion thereof with a radius of curvature substantially matching a corresponding conveyor roller. A portion of the first side wall extends toward and joins the second side wall, the second side wall further having a tail portion and a living hinge extending away from the tail portion.

Conveyor system bridge

A lifter assembly includes first and second lifter segments movably attached to one another and defining a lifting channel having an expandable bladder contained therein. Each lifter segment has an arm extending away from a base of the lifter segment and a travel stop at a distal end of the arm. Each lifter segment further has a keyway opening. The keyway opening of the first lifter segment receives the arm of the second lifter segment and the keyway opening of the second lifter segment receives the arm the first lifter segment.
