Abstract
An apparatus and method for cutting and threading a sheet of material is described. The apparatus can facilitate the transfer of a sheet from a sheet forming machine to a processing machine, and can halt the feeding of sheet material to the processing machine. When the processing machine is ready to receive more sheet material, the apparatus cuts the sheet and feeds the newly formed sheet to the processing machine.
Claims34
An apparatus for cutting and threading a sheet material, comprising:
- a feed roll;
- a scrap roll;
- a first shoe, capable of contacting a sheet of material to the scrap roll;
- a second shoe, capable of contacting a sheet of material to the feed roll;
- and
- a knife;
- wherein the knife impacts and cuts the sheet when the sheet is in contact with the scrap roll and the first shoe, and when the sheet is in contact with the feed roll and the second shoe.
An apparatus for cutting and threading a sheet material, comprising:
- a frame;
- an anvil roll;
- and
- a knife roll;
- the anvil roll and knife roll movably mounted to the frame to provide an arcuate motion to the rolls at least between a first position and a second position;
- wherein a sheet of material is directed to a processing apparatus by passing between the anvil roll and the knife roll in the first position;
- the sheet of material is directed away from the processing to apparatus by passing between the anvil roll and the knife roll in the second position;
- and
- the sheet of material is cut by the convergence of the knife roll and anvil roll.
An apparatus for cutting and threading a sheet material, comprising:
- a transfer blade having a retracted position and an extended position;
- and
- a pair of nip rolls;
- wherein a sheet of material passing between the retracted position and the extended position is diverted away from a processing apparatus by passing between the nip rolls;
- and
- the movement of the transfer blade from the retracted position to the extended position directs the sheet toward the processing apparatus.
An apparatus for cutting and threading a sheet material, comprising:
- means for directing a sheet toward a processing apparatus;
- means for cutting the sheet;
- means for directing the sheet away from the processing apparatus;
- and
- means for simultaneously cutting the sheet and directing the sheet toward the processing apparatus.
A method for handling a sheet of material, comprising:
- providing a formed sheet of material;
- breaking the sheet of material to form an initial edge to the formed sheet and a scrap portion;
- directing the initial edge to a processing machine;
- and
- diverting the scrap portion away from the processing machine;
- wherein the breaking, directing, and diverting are automatically controlled such that the providing is a continuous process.
