ABSTRACT:
In an apparatus for joining the ends of belt-shaped materials which comprises a front end lower pawl and a front end upper pawl which are driven to hold the front end portion of a first belt-shaped material and a rear end lower pawl and a rear end upper pawl which are driven to hold the rear end portion of a second belt-shaped material, so as to butt-join the front end of the first belt-shaped material and the rear end of the second belt-shaped material. The rear end lower pawl and the rear end upper pawl have rear end protrusions arranged like the teeth of a comb and which protrude towards the front end lower pawl and the front end upper pawl, respectively. The front end lower pawl and the front end upper pawl also have front end protrusions arranged like the teeth of a comb and which protrude towards the rear end lower pawl and the rear end upper pawl, respectively. As a result, when the rear end lower pawl and rear end upper pawl and the front end lower pawl and the front end upper pawl are moved towards each other, the front end protrusions and the rear end protrusions are intertwined with each other, thus providing planar surfaces to support the junction of the belt-shaped materials.
