Abstract

A device including blades and pins is mounted for interaction with a bedroll for separating or cutting a web or sheet of material as the web travels around the circumference of the bedroll. The assembly comprises a clamp having a bottom side and a front side. Two blades having an upper surface and a lower surface are provided, with a blade spacer located between the blades, and operably connected to the clamp. A blade from a nearby chopper roll is adapted to engage the blades of the device to separate a sheet as it travels along the processing pathway. A unitary elongated mandrel that is fixed in relation to the blade, and configured to carry or move a severed web, is provided. The unitary mandrel employs a strut from which projections or pins extend in a line or row, the pins being adapted to pierce and carry the severed tail of the web to a core for gluing the tail to the core, followed by winding.

Claims6

Dependent claims

A web severing and carrying apparatus including a mandrel that comprises a pin assembly projecting therefrom, comprising:

a bedroll rotatably supported on a frame for rotation about an axis, the bedroll having an outer surface for contacting a web,
a mandrel with a pin assembly projecting therefrom, the pin assembly being movably mounted on the bedroll, the pin assembly being movable between a first position in which the pin assembly is inward of the outer surface of the bedroll and a second position in which the pin assembly projects beyond the outer surface of the bedroll for contact with the web,
wherein the pin assembly comprises at least two blades configured for severing a web and having multiple spaced pins along its length, in which the pins are configured for piercing and carrying the web;
and
a clamp for mounting the mandrel to the bedroll, the clamp including a front surface that faces the outer surface of the bedroll when the pin assembly is inward of the outer surface, the mandrel being connected to the front surface of the clamp.
