Abstract
A thread withdrawn from a bobbin is passed along a straight line through a plate brake. A base brake plate is driven by a drive extending outside the periphery of the base brake plate. A tensioning device removably attached to a top brake plate is connected therewith by a ball snap-type connection. It comprises a first compression spring with one end supported at a gripping sleeve and slideable along a pressing pin surrounded by this compression spring. The gripping sleeve is connected to a displaceable control plate extending parallel to the pressing pin. This control plate permits a simultaneous variation and adjustment of the pressure exerted by a number of such similar tensioning devices. A second compression spring surrounding the pressing pin is supported at a side of the gripping sleeve remote from the first compression spring and counteracts the first compression spring, so that the difference of the spring forces acts upon the top brake plate. This difference can be continuously adjusted from a negative value through zero to a positive valve by displacing the control plate, and thus, the position of each gripping sleeve relative to the pressing pin.
