A shearing device () having a blade () with at least one blade cutting edge () which is helically coiled, and rotatable, about an axis of rotation (R) of the blade (). The blade cutting edge () is assigned a counterpart blade cutting edge () of a counterpart blade (). The shearing movements, by which for example bristle filaments () of brushes () for machining can be cut to length, are generated by relative rotational movement of the at least one helically coiled blade cutting edge () with respect to the preferably static counterpart blade cutting edge () of the counterpart blade (). Since the blade () and the counterpart blade () can keep their spacing to one another constant during operation, there is a relatively low risk of injury during the use thereof.

Shearing device and brush production machine with shearing device, and use of a shearing device

An apparatus for producing round brushes, which have bristles twisted in between two portions of a folded wire. The apparatus has a bristle feeding device and a rotary gripper for twisting two portions of wire with bristles located therebetween, a deflecting device with two deflecting rollers spaced apart in the longitudinal direction of the wire. The rotary gripper is linearly displaceable transversely in relation to the longitudinal direction of the wire, for gripping the folded region of the wire that is formed by force being applied by an application element that is adjustable between the deflecting rollers transversely in relation to the longitudinal direction of the wire. A bristle feeding device, for feeding bristles to the bent-around portions of wire, is provided in the region of the deflecting rollers. In the region of the unfolded portions of wire there is provided a device for slowing the advancement of the wire.
