Drawing unit upper roller holder

摘要

The plastics holder for the upper rollers of a drawing unit, in a spinning assembly, has a switch eccentric (12) to move one of the two spring plates (8,9) in an axial sliding action to adjust the loading forces in the holder. Elasticity is given by an elastic tongue (11), injection moulded in place, to compensate the switching movement of the sliding spring plates (8,9).The switch eccentric (12) is placed in the holder and the carrier and loading arm (1), or supports the holder, and is set at the arm (1) by a dedicated switch tool.
