ABSTRACT:
A multispindle thread cutter apparatus is proposed, which has a drive shaft (3) to be driven by motor and which has a plurality of work spindles (4). Interposed between the drive shaft (4) and the work spindles (4) is a distributor and reversing gear (33), by way of which the work spindles (4) are driven to rotate by the drive shaft (3). Each work spindle (4) is assigned its own single reversing coupling (34), which has its own single switchover device (35), so that the directions of rotation of the work spindles (4) can be reversed while the drive shaft (3) continues to rotate uninterruptedly in the same direction.
