Abstract

Apparatus for applying leading tips to a continuous sheet material and then cutting the same comprises a rotatable cut drum, a cutting knife contained in the cut drum and adapted to be caused to project outwardly through the surface of said cut drum at a fixed position while said knife is rotating together with the cut drum, a cam mechanism secured to a stationary member outside the cut drum for actuating said cutting knife, a single position clutch adapted to be rotated in synchronism with the cut drum, a mechanism adapted to be driven through said single position clutch for applying leading tips to the continuous sheet material, the arrangement being such that the continuous sheet material is fed along said leading tip applying mechanism and the outer periphery of the cut drum as the cut drum is rotated and that said single position clutch is energized into its connectible condition at predetermined time during the operation, while said cam mechanism is switched to a cammable condition in which it is able to perform its camming action during not more than one complete revolution of cut drum when the continuous sheet material is further transferred a fixed length from the time of application of the leading tip, so that the knife within the cut drum is actuated to cut the sheet material which is running along with the rotation of the cut drum.
