Abstract
A device for discarding trims formed by cutting machines during the cutting of paper logs, including an advancing plane on which paper rolls (R) and trims (RT, RC) advance along a given direction (A), wherein the trims can fall through a discontinuity provided on the advancing plane. The advancing plane is formed by a first extendible conveyor (1) and a second extendible conveyor (2). Each of the conveyors (1, 2) is connected with an extension and retraction device. The discontinuity on the advancing plane is realized or eliminated depending on the extended or not extended configuration of the conveyors (1, 2).
Claims20
A device for discarding trims formed by cutting machines during the cutting of paper logs, the device comprising:
- an advancing plane on which paper rolls and trims advance along a given direction, wherein the trims can fall through a discontinuity provided on said advancing plane, said advancing plane being formed by a first extendible conveyor and a second extendible conveyor, each of said conveyors being connected with respective extension and retraction means, said discontinuity on the advancing plane being realized or eliminated depending on the extended or not extended configuration of said conveyors.
A device for discarding trims formed by cutting machines during the cutting of paper logs, the device comprising:
- a first conveyor;
- a second conveyor;
- a first extension and retraction means connected to said first conveyor for moving at least a portion of said first conveyor between a first conveyor first position and a first conveyor second position;
- a second extension and retraction means connected to said second conveyor for moving at least a portion of said second conveyor between a second conveyor first position and a second conveyor second position, said first conveyor and said second conveyor defining an advancing plane on which paper rolls and trims advance with at least in said first conveyor first position and said second conveyor first position, said first conveyor and said second conveyor defining a gap in said advancing plane with at least said second conveyor in said second conveyor second position.
A device for discarding trims formed by cutting machines during the cutting of paper logs, the device comprising:
- a first conveyor;
- a second conveyor;
- a first conveyor moving means connected to said first conveyor for moving at least a portion of said first conveyor in a direction of an advancing direction of rolls and trims and a direction opposite the advancing direction of the rolls and trims such that said at least said portion of said first conveyor moves between a first conveyor first position and a first conveyor second position;
- a second conveyor moving means connected to said second conveyor for moving at least a portion of said second conveyor in the direction of the advancing direction of the rolls and trims and the direction opposite the advancing direction of the rolls and trims such that said at least said portion of said second conveyor moves between a second conveyor first position and a second conveyor second position, said first conveyor and said second conveyor defining an advancing plane for advancing the rolls and trims, said first conveyor and said second conveyor defining a gap in said advancing plane with at least said portion of said second conveyor in said second conveyor second position.
