Drawing head for drawing machine with head part establishing angular direction

摘要

The second head part is provided with projections (22), and can be moved in and out of engagement with the corresp. locking recesses (12). The locking system has n(greater than 1) projections (22), which are spaced from each other at a whole number multiplication of the basic spacing (g), plus an auxiliary angle (g/n). One of the projections (22) at least or at least one sub-group of projections (22) is movable by a disengaging unit (32-48) in to a rest position, in which the locking recesses (12) cannot work together with the locking recesses (12). The projections (22) are carried by locking levers (20), which respectively are preloaded respectively by a spring (28) in a working position working together with the locking recesses (12).
