The transport device 10, illustrated in the figure, includes a belt 11 trained over a drive pulley 12 and a pair of idlers 13. Another belt 15 is trained over idlers 16 and 17, with a stretch of the belt running in contact with belt 11 to form the transport path. Belt 15 is driven by the contact with belt 11. Belt thickness, hardness and size are selected to accommodate the size and shape of the part to be transported. The belt surfaces which run in contacting, confronting relation may be coated with soft foam bonded to the harder belt material to handle delicate parts. The inner belt 11 is tensioned by varying the position of idlers 13 to effect the correct drive relationship, and the outer belt 15 is tensioned by adjusting idlers 16 and 17 to enable part pickup and retention without part damage.
