Abstract
A band clamping device for a machine wrapping or strapping a band, strip or the like about piece goods, such as boxes, containers, packages, crates and so forth, especially a plastic band or strip, comprising a stationary clamping jaw and a movable clamping jaw guided for movement towards and away from the stationary clamping jaw. The movable clamping jaw is articulated at an end hinge of a first element of a toggle lever, a second element of which can be pivoted by means of a drive about a further end hinge. Both clamping jaws possess essentially flat clamping surfaces intended to engage at the band and to hold such against the action of a tension or traction force. The connection line between the hinge points of the toggle lever together with the clamping surface of the clamping jaws enclose an acute angle open in the direction of the tension or traction force and the guide of the movable clamping jaw is elastically resilient in such direction.
