Abstract
A casing brake is disclosed for use in combination with a generally tubular stuffing horn over which casing is released for filling with material discharged from the horn. The brake is of the type which includes a rigid housing which retains a deformable insert that fits over the horn and cooperates with the horn to engage the casing against the horn. Thus casing brake includes a first annular insert that has a throughbore with a circumferential groove on the inside of the throughbore with a second annular inner member which is comprised of a helical coil positioned within the groove, the inner member preferably being comprised of polytetrafluoroethylene with the outer member being elastically deformable with respect to the inner member to thereby alter the effective diameter of the groove causing an increase or decrease the diameter of the coil which, in turn, more loosely or more tightly grips the outside surface of the casing as it passes over the horn.
