Abstract
A device for machine-making a dunnage product from a single- or multi-ply continuous paper web may include a delivery conveyor configured to draw the paper web into the device in a conveying direction; a cutter configured to separate the dunnage product from a three-dimensional strand of dunnage material formed from the paper web within the device; and a removal conveyor positioned after the cutter in the conveying direction and configured to remove the separated dunnage product from the cutter.
Claims20
A device for machine-making a dunnage product from a single-ply or multi-ply paper web, the device comprising:
- a delivery conveyor configured to draw the paper web into the device in a conveying direction;
- a cutter configured to separate the dunnage product from a three-dimensional strand of dunnage material formed from the paper web within the device;
- and
- a removal conveyor positioned after the cutter in the conveying direction and configured to remove the separated dunnage product from the cutter, wherein:
- the removal conveyor comprises a wheelwork having two conveying wheels laterally opposite one another relative to the conveying direction, the two conveying wheels comprising a wheel-center-to-wheel-center distance being undersize relative to wheel diameters of the two conveying wheels such that the two conveying wheels overlap in a radial direction, the two conveying wheels being elastically biased against each other, and
- respective axles of the two conveying wheels of the removal conveyor are offset with respect to each other relative to the conveying direction such that a first axle of a first of the two conveying wheels of the removal conveyor is located farther downstream in the conveying direction than a second axle of a second of the two conveying wheels of the removal conveyor.
A device for machine-making a dunnage product from a single-ply or multi-ply paper web, the device comprising:
- a delivery conveyor configured to draw the paper web into the device in a conveying direction;
- a cutter configured to separate the dunnage product from a three-dimensional strand of dunnage material formed from the paper web within the device;
- and
- a removal conveyor positioned after the cutter in the conveying direction and configured to remove the separated dunnage product from the cutter, wherein:
- the delivery conveyor and/or the removal conveyor comprise a wheelwork having two conveying wheels laterally opposite one another relative to the conveying direction, the two conveying wheels comprising a wheel-center-to-wheel-center distance being undersize relative to wheel diameters of the two conveying wheels such that the two conveying wheels overlap in a radial direction, the two conveying wheels being elastically biased against each other, and
- the cutter comprises:
- a perforator tool configured to introduce a perforation into the strand of dunnage material, the perforator tool comprising at least one perforator nose, at least one perforator reception, and at least one stripper, wherein:
- the at least one perforator nose and the at least one perforator reception are associated with one another such that, for perforating, the at least one perforator nose is configured to extend and retract relative to the at least one perforator reception, and/or
- the at least one stripper is associated with the at least one perforator nose and/or with the at least one perforator reception such that upon retraction of the at least one perforator nose, the perforated dunnage product is removed from the at least one perforator nose and/or from the at least one perforator reception.
