Claims14
A sheet material wrapping device for producing an elongated support member having a plurality of wrapped layers, comprising:
- a forming unit having winding arms operatively connected to a rotatable shaft of a motor, wherein the winding arms are each rotatable about a rotational axis and adapted to wind a sheet material from a sheet source into a support member having one or more wrapped layers, wherein the forming unit comprises a clamp assembly including a clamp operatively movable in relation to and engagable with one of the winding arms to hold a portion of the sheet material between the clamp and the winding arm during at least a portion of rotation of the winding arms;
- an end cutting device comprising a cutting member adapted to cut the sheet material at an angle from 0° to about 45° measured with respect to a direction perpendicular to a feed direction of the sheet material;
- and
- a holding member device including a holding member that is adapted to contact the sheet material during a cutting operation, and wherein the holding member device directs an end portion of the sheet material between one of the winding arms and clamp after a cutting operation has been performed.
