A cutting unit in a packaging machine for separating a series of finished packages containing a predetermined number of products from a continuous packaging or bundle advancing on a conveyor, comprising a frame, which supports a pair of side cutting blades and a pair of upper cutting and lower cutting blades arranged facing four sides of the continuous bundle, wherein the two pairs of blades can be alternately moved forward and backward between a rest position separated from the continuous bundle, and an engagement position on the continuous bundle containing groups of the products arranged on two flanked rows and wrapped in a film of extendable plastic material, each pair of blades being driven in an alternating forward and backward movement for engagement with and disengagement from the continuous bundle by a double crank actuated by a single motor.

A cutting mechanism for a composite material lay-up head comprises a plurality of blades, each blade having a variable width, and a drive mechanism to drive the blades along an axial direction to cut a respective tow of composite material. The blades are rotatable about the axial direction between a first angular position, wherein the blades sever the respective tow along a first cutting direction transversal to a longitudinal direction of the respective tow, and a second angular position, wherein the blades sever the respective tow along a second cutting direction rotated by a rotation angle to the first cutting direction.

An incision station for making a plurality of weaknesses respectively on a plurality of portions of a web, for producing a plurality of packages each of which including a supporting sheet corresponding to a respective portion of the portions and an opening system corresponding to the weakness made on the respective portion, which makes it possible to increase the precision in obtaining the opening system of each package and to increase the productivity of the packaging machine in which the above-mentioned station operates. This invention also relates to a packaging machine which includes the incision station and a incision method for making the above-mentioned plurality of weaknesses, in such a way as to achieve the above-mentioned aims.

A hand-held and operated device for splitting rehabilitative elastic tape into segments and rounding corners of the rehabilitative elastic tape segments and method of use is disclosed. The device comprises a feed roll of rehabilitative elastic tape, and a housing. The housing is comprised of a vertical cutting mechanism and a cutting die punch mechanism operably coupled in tandem. There are a plurality of actuator buttons operably coupled to and aligned with the blades for setting the blades to either a cutting position or a non-cutting position. The cutting die punch mechanism is comprised of a pair of mating tools, a die punch and a cutting die. The die punch is adapted to be moved into the cutting die by hand and attain the closest possible mating of said members for cutting or forming the rounded corners of a tape segment when the tape is fed into the punching mechanism.

A cutter device, comprising: a first blade including a first cutting edge extending in a first direction; a second blade including a second cutting edge extending in a second direction; and a guide portion provided at a position anterior to the second blade in the second direction, wherein the second blade moves in the second direction to cut a recording medium while leaving a part thereof uncut, and when the second blade is located posterior, in the second direction, to a position where the second blade cuts the recording medium, at least a part of the guide portion is located to protrude farther in the first direction than the first cutting edge, or located at a same position as the first cutting edge.

A tape detection mechanism including a first pivoting member provided to pivot about a detection pivoting shaft, a second pivoting member linked, to be configured to pivot, to a pivot linking portion provided on the first pivoting member, a pivoting contact section with which the second pivoting member comes into contact when the first pivoting member and the second pivoting member pivot in a first pivoting direction about the detection pivoting shaft as the tape, which is fed thereto, comes into contact with the first pivoting member, and a sensor which detects the second pivoting member which comes into contact with the pivoting contact section.
