ABSTRACT:
The invention concerns a device for maintaining the relative phase shift between an endless conveyor and a rotary or rotatingly indexing table and/or additional conveyors attached thereto, wherein the endless conveyor has a fixedly journalled drive wheel and a displaceably journalled tensioning wheel, process tools e.g. holders, jaws and similar fixtures being attached to the conveyor at equal spacing along its length and being associated with the rotary or indexing tables and/or additional conveyors elements driven synchronously, by means of a common drive, with the conveyor, the drive shafts of the table(s) and/or additional conveyors being linked by a shaft coupling, consisting of an axially fixed sleeve and an axially movable sleeve, the sleeves having complementary helicoidal bearing surfaces with a predetermined pitch of thread, and a transmission, a predetermined transmission ratio connecting the displaceably guided bearing of the sprocket wheel and the axially movable sleeves of the shaft coupling.
