Stripping device for a press
First Claim
1. A stripping device for stripping a waste piece from a sheet of material, the device comprising:
- a) a stripping member having a connecting portion, a supporting finger located on one side of the connecting portion, and a stripping finger located on another side of the connecting portion;
b) the supporting finger having a first end connected to a frame, the supporting finger being movable about the first end with respect to the frame;
c) the stripping finger having a stripping end portion, the stripping end portion being biased away from the supporting finger for contacting at an angle the waste piece to be stripped, the supporting finger being deflectable away from the waste piece, the stripping end portion being movable further away from the supporting finger and against the waste piece so as to strip the waste piece.

Abstract
A stripping device for stripping a waste piece from a sheet of material, which includes a stripping member with a connecting portion, a supporting finger located on one side of the connecting portion, and a stripping finger located on another side of the connecting portion. The supporting finger has one end connected to a frame and is movable about its end with respect to the frame. The stripping finger has a stripping end portion, which is biased away from the supporting finger and contacts the waste piece at an angle. The supporting finger is deflected away from the waste piece and the stripping end portion is moved further away from the supporting finger and against the waste piece to strip it from the sheet.

43. A stripping device for use in a die cutting press, for stripping a waste piece from a pre-cut sheet, the press having a first frame having at least one frame opening therein and a second frame having at least one punch complementary with the frame opening, the frames being movable with respect to each other, the punch being cooperable with the frame opening, the device comprising:
-
a) a folded over piece of resilient material having a supporting finger located on one side of the fold, and a stripping finger located on another side of the fold, the supporting finger having a first end connected to the first frame, the supporting finger being movable about the first end with respect to the first frame, the stripping finger having a stripping end portion, the stripping end portion being resiliently biased away from the supporting finger for contacting at an angle the waste piece to be stripped, the supporting finger being deflectable away from the waste piece, the stripping end portion being movable further away from the supporting finger and against the waste piece so as to strip the waste piece;
b) a blocking member for blocking the waste piece after it has been stripped, the blocking member having a second end connected to the frame and a pair of blocking fingers resiliently hinged to the second end, the blocking fingers being spaced apart to define a gap therebetween, the gap being of sufficient size to permit the stripping end portion to move between the blocking fingers. - View Dependent Claims (44, 45)

46. A stripping device for use in a die cutting press, for stripping a waste piece from a pre-cut sheet, the press having a first frame having at least one frame opening therein and a second frame having at least one punch complementary with the frame opening, the frames being movable with respect to each other, the punch being cooperable with the frame opening, the device comprising:
-
a) a folded over piece of resilient material having a supporting finger located on one side of the fold, and a stripping finger located on another side of the fold, the supporting finger having a first end connected to the first frame, the supporting finger being movable about the first end with respect to the first frame, the stripping finger having a stripping end portion, the stripping end portion being resiliently biased away from the supporting finger for contacting at an angle the waste piece to be stripped, the supporting finger being deflectable away from the waste piece, the stripping end portion being movable further away from the supporting finger;
b) a blocking member for blocking the waste piece after it has been stripped, the blocking member having a stationary finger fixedly connected to the second frame, the stationary finger being spaced apart from the punch and defining a blocking gap therebetween, the stationary finger includes a planar surface, the stationary finger being tapered away from the second frame towards the planar surface, the stripping finger being slidable along the planar surface against the waste piece towards the blocking gap so as to strip the waste piece.

47. A method of stripping a waste piece from a sheet of pre-cut material, the method comprising:
-
a) biasing a stripping finger away from a supporting finger, the stripping finger being in contact with the waste piece at an angle;
b) deflecting the supporting finger away from the waste piece so as to strip the waste piece from the sheet. - View Dependent Claims (48, 49, 50)
