ABSTRACT:
A pallet type conveyor including elongated frames which constitute linear pathes of pallets with continuously driven endless chains. A pallet is driven with the endless chain by the adhesive friction between rectangular attachments and adhesive friction plates. The pallet has apertures wherein adjusting bolts are respectively and rotatably secured to the pallet and mate with spring stop nuts engaged with coil springs biasing a friction plate. When the adhesive friction between the attachments and the friction plate is needed to be increased in response to a heavier workpiece carried by the pallet, a worker can remove the pallet from the frame and rotate the adjusting bolt clockwise to adjust the elasticity of the spring caused the adhesive friction in response to the workpiece.
