A self-propelled cutter has a gear assembly to provide both downward and forward force on a material to be cut. A gear assembly includes a drive input gear that engages with a transfer gear and propulsion gear engaged with the transfer gear by a lever arm. The drive gear and transfer gear are coupled and fixed to the cutter body but the propulsion gear rotates about the transfer gear via the lever arm. This gear assembly enables the propulsion gear to move as required to provide both downward and forward force on a material to be cut, such as a cast. A self-propelled cutter may have a drive input that is coupled with a drive input device, such as a crank or an electric motor. A cutter may have a first gear assembly on a first side of the cutter body and a second gear assembly on a second side.

A method for perforating a web with a perforating apparatus includes: rotating a cylinder about a longitudinal cylinder axis, wherein the cylinder comprises at least one shaped blade; operatively engaging a movable support with the cylinder; positioning an anvil disposed on the support so as to cooperate in contacting relationship with the shaped blade, wherein at least one of the blade and the anvil comprise a plurality of teeth, and wherein adjacent teeth are separated by a recessed portion; feeding a web between the cylinder and the support; and perforating the web as the anvil cooperates in contacting relationship with the shaped blade disposed on the rotating cylinder.

A suction cutting conveyor of an automatic blade cutting machine for sheet materials, including a plurality of cutting supports rigidly connected to a drive mechanism driven along rectilinear and curvilinear trajectories, each cutting support including a plurality of bristles each having a foot rigidly connected to a sole and a head opposite to the foot and on which a sheet material to be cut is intended to rest, the sole of each cutting support being capable of being able to elastically deform following the trajectories of the drive mechanism.

A reinforced folding cutting mat including a mat, which is a plate body thicker than 0.5 mm. The mat is formed with at least a cutting face made of cutting resistant plastic material. At least a fold tangent is formed in at least one part of mat, so that the mat can be bent using the fold tangent as fold line, and the one fold tangent includes a plurality of deep cutting edges and a plurality of reinforcing ribs with different cutting depths. The reinforcing ribs are adjacent to the deep cutting edges. The folding cutting mat is a product a one-piece product that is reinforced and has a more durable fold tangent form.

Present invention teaches double-sided magnetic cutting deck. A plurality of magnets are used on both sides of a PC center board, sandwiched by an upper and a lower board, and bonded by TPU glue, which is also the same material used on the upper and lower boards. The magnets are substantially the size of the holes, so as to fit snuggly into the holes, with gap spaces between the edges of the hole to hold excess TPU glues, for better bonding of the magnets in place. Using the TPU materials on the surface (of upper and lower boards) provides longer product life due to the good resilience to physical force from the cutting impressions made during normal use.

A padding system mountable on a working surface of a die press device to provide a cushion for die cutting includes one or more padding blocks, each of the one or more padding blocks including a backing layer and a padding layer. The backing layer is composed of a flexible magnetic material and the padding layer is composed of a soft cushion material. The padding layer is bonded to the backing layer.

A packaging line station having a frame, a die assembly, a drive motor, and an anvil roller. The frame has a base with two vertical stanchions extending upwardly from sides thereof and a top cross-member affixed across the stanchions. The die assembly includes a yoke affixed to the cross-member, a die wheel rotatably affixed to side arms of the yoke, a drive shaft affixed to the die wheel and a cutting die affixed to the die wheel. The drive motor is connected to the drive shaft. The drive shaft and the anvil roller extend between the stanchions. The cutting die and the anvil roller and spaced apart by a nip for receiving a traveling web. As the web passes through the nip the web is cut by blades of the rotating die to form a slit. An adhesive resealable tape or label is then applied over the slit.
