The present disclosure is directed to a method for cutting a coreless rolled paper product. The method includes defining a core offset value for a cut, the cut having a starting point and an ending point, setting a plunge speed for a saw to a first plunge speed, and changing the plunge speed to a second plunge speed when the saw reaches the core offset value.

A cutting device (1), in particular for rapidly cutting webs, comprising: a support structure (2) comprising a fixed blade (3), a carriage (4) movable along a movement direction (X), a mobile blade (5) mounted on the carriage (4), a guide (7), associated to the support structure (2), on which the carriage (4) is slidable along the movement direction (X); a sliding sleeve (11), interposed between the carriage (4) and the guide (7) concentrically to the guide (7); seal means (8, 10) interposed between the guide (7) and the carriage (4) so as to define a chamber (9), concentric to the guide (7) and containing the sleeve (11); motor means (6) configured to move the carriage (4) according to an alternating movement along the movement direction (X) between a non-operating position and an operating position, in which the mobile blade (5) partially superposes the fixed blade (3) so as to carry out the cutting of a web; supply means (15) for supplying air to the chamber (9) so as to maintain it at a greater pressure with respect to the surrounding environment.

A cutting die for rotary die-cutting of a label laminates is described herein. The cutting tools of the die include at least one of the following cutting edge parameters: effective height, shape and bevel angle arranged to be different in a first direction when compared to a second direction of the cutting die. The use of the cutting die, a method for designing a cutting die and a method for die-cutting a label laminate are also described.

The machine includes a feeding path for the logs to be cut and a cutting head arranged along the feeding path. The cutting head includes a coupling for a disc-shaped cutting blade and is designed to impart the disc-shaped cutting blade a rotary motion around the axis thereof and a cyclic movement to cut the logs into single rolls, and to allow the logs to move forward along the feeding path. The machine also includes at least a grinding unit, including at least one grinding wheel mounted onto a rotation shaft and co-acting with a side of the disc-shaped cutting blade to grind the cutting edge of the same disc-shaped cutting blade. A controlled approach system is also provided to move the grinding wheel towards the disc-shaped cutting blade.

The invention concerns a cutting device (1) for reducing the width of a ready-made roller blind blank (28) comprising a roller tube onto which a fabric has been wound. The cutting device (1) comprises a mandrel (13), which is adapted to be inserted into and hold an end to be cut of the roller tube, and a knife arrangement, which is adapted to circumferentially cut first the fabric wound on the roller tube and then the roller tube on the mandrel (13) such that the width of the ready-made roller blind blank (28) is reduced. The invention also concerns a ready-made roller blind blank (28), which comprises a roller tube, onto which a fabric has been wound and which is adapted to be cut by means of a cutting device (1) according to the invention. For this the roller blind blank (28) comprises a disposable wrapping, which bears a visible measurement scale along at least one end portion of the roller blind blank (28).

The invention relates to a connecting cut assembly for producing connecting cuts in a material web being conveyed. The connecting cut assembly comprises at least one knife device with a cutting knife for cutting engagement with the material web to produce a connecting cut in the material web. Moreover, the at least one knife device has an actuatable cutting knife angle adjusting device for setting a respective cutting knife angle of the cutting knife to the material web. The connecting cut assembly comprises at least one presetting unit for actuating the respective cutting knife angle adjusting device.

The device comprises a log advancing path and a set of jaws in the form of double four-bar linkage, with an adjusting mechanism to adjust the position of the jaws according to the diameter of the logs to be cut.

The present invention is a rolled paper cutting device and method which safely and easily cuts a variable length sheet of paper from rolled paper, including an adjustable holder for controlling the rolled paper, and a paper cutting blade embedded within a safety slot, the safety slot protecting a user from a blade related injury.

A cutting portion (cutting device) includes a fixed blade that extends in an intersecting direction (X axis direction) intersected with a transport direction transporting a roll paper, and a round blade that cuts the roll paper by relatively moving in the intersecting direction (X axis direction) with respect to the fixed blade in a state of being abutted on the fixed blade, in which the fixed blade extends over a portion of a range where the round blade relatively moves, and the round blade is in a separation state of being separated from the fixed blade in the transport direction when entering a region facing the fixed blade (cutting operation region) from a region not facing the fixed blade (standby region).

Provided herein is a paper cutter, including: a paper cutter housing which includes an accommodating space for accommodating a roll of paper to be cut, where a side wall of the paper cutter housing further includes two parallel guide rails, a holding portion is arranged on an outer wall of the paper cutter housing, and a pressure direction of the holding portion is capable of being perpendicular to a plane formed by the two parallel guide rails; and a paper cutting device which is connected to the side wall of the paper cutter housing and includes a cutter assembly, where the cutter assembly includes an object picking member and a cutter, and a direction corresponding to a cutting edge of the cutter is opposite to a paper feeding direction of the paper to be cut.
