ABSTRACT:
A conveyor for transporting articles placed in series thereon includes a conveyor track of extruded high density polyethylene having an upwardly opening inverted T-shaped longitudinal slot therein and an endless conveyor chain slidably engaged in the slot with integral chain tabs extending laterally outwardly into lateral slot recesses from selected links of the conveyor chain so as to retain the chain against lateral, vertical or torsional displacement with respect to the slot. The conveyor chain projects above the opening of the slot to support the conveyed articles and bears on an upstanding central rib on the slot bottom and, through its tabs, on the lateral recess bottoms. Convergent notches in corresponding ends of successively end-abutted track members making up the track guide the chain tabs into the slot recesses without interference from track member end faces due to slight misalignment of track members. A chain drive mechanism drives the chain in a continuous loop along the conveyor track and along a return path underneath the track.
