A long separator sheet (12a, 12b) has a right edge part (12c) that is in a trapezoidal shape and a left edge part (12d) having a curved shape. Therefore, it is possible to provide a long porous separator sheet which satisfies both a good electrolyte take-in property (i.e., liquid absorption property) and a good electrolyte retaining property (i.e., liquid retention property).

In a cutting device for cutting a round, a transparent substrate is arranged on an object to be cut. A sleeving tube is arranged on the transparent substrate. An end of a transverse rod penetrates through the sleeving rod and extends to over the object. The position of the transverse rod in the sleeving rod is adjusted by a locking member. The other end of the transverse rod is fixed to a cutting assembly. The cutting assembly selectively touches the object. A rotating assembly is combined with the transparent substrate and penetrates through the transparent substrate. When the rotating assembly is pressed to touch the object and the rotating assembly rotates on the object to rotate the transparent substrate, the transverse rod moves the cutting assembly to perform a round-cutting operation on the object or paint a round line on the object.

A slotter apparatus includes blade-attached slotter heads, receiving slotter heads, a drive device, a movement device, and a control device. The blade-attached slotter heads include slotter knives mounted on outer peripheral portions of the blade-attached slotter heads, are rotatably supported, and are disposed along a sheet transport direction. The receiving slotter heads are rotatably supported, are disposed to face the blade-attached slotter heads, and are disposed in the sheet transport direction in series. The drive device drivingly rotates the several blade-attached slotter heads and the receiving slotter heads. The movement device moves the blade-attached slotter heads and the receiving slotter heads in a rotational axis direction. The control device controls the drive device or the movement device when an adjustment mode in which each of the slotter knives is positioned at a predetermined position set in advance is selected.

The invention relates to a system and process for producing a spiral food product on a skewer, such as twister potato. The system thereto comprising a clamping element for clamping the food product, a guiding structure for guiding a skewer towards the centre region of the clamped food product, a pusher for pushing the skewer away from the guiding structure such that the skewer pierces the food product and a rotatable knife for cutting the food product in a spiral manner.

The versatility of a slotter device, a sheet slicing method and a carton former is improved by providing first slotter heads and first lower blades, first slotter knives and second slotter knives mounted on the circumferences of the first slotter heads, second slotter heads and second lower blades, third slotter knives and fourth slotter knives mounted on the circumferences of the second slotter heads, third slotter heads and third lower blades, and fifth slotter knives and sixth slotter knives mounted on the circumferences of the third slotter heads, to process cuts of differing lengths.

The disclosure concerns a rotary cutting apparatus having a frame and a die roll defining a first longitudinal axis and having a cutting member. The die roll is rotatably connected with the frame and configured to rotate about the first longitudinal axis. The rotary cutting apparatus further has a bearer ring connected with the die roll and an anvil roll defining a second longitudinal axis and having an outer radial surface. The anvil roll is rotatably connected with the frame and is configured to rotate about the second longitudinal axis. The bearer ring of the die roll is in contact with the outer radial surface. The anvil roll may be supported by at least one cam follower. The anvil roll may be axially removable from the frame via lateral translation along the second longitudinal axis.

The present invention relates to a cutting bite and a cutting apparatus including the same. According to one embodiment of the present invention, a cutting bite is provided to sequentially pass through an upper end portion, a central portion, and a lower end portion of stacked films in a thickness direction of the stacked films when a rotating wheel rotates, and is provided such that cutting is performed in a manner in which a cutting direction of a cutting tip is a direction from an outside toward an inside of the stacked films while the cutting bite passes through the upper end portion toward the lower end portion.

The cutting system is configured to cut a continuous strip which extends lengthwise in a longitudinal direction and widthwise between a first edge and a second edge into strips. The cutting system includes a drive device which imparts to the continuous strip a feed speed, a first cutting roller and a contrarotating second cutting roller that cooperate to cut the continuous strip across its full width. The first cutting roller is provided with a first helical blade and is driven in rotation A variable synchronizer makes it possible to select and to modify the synchronization ratio between the rotational speed of the first cutting roller and the non-zero forward speed of the continuous strip in such a way as to be able to adjust the cutting angle according to which the cross-section of the continuous strip is oriented with respect to the longitudinal direction of the continuous strip.

The invention relates to a system and process for producing a spiral food product on a skewer, such as twister potato. The system thereto comprising a clamping element for clamping the food product, a guiding structure for guiding a skewer towards the centre region of the clamped food product, a pusher for pushing the skewer away from the guiding structure such that the skewer pierces the food product and a rotatable knife for cutting the food product in a spiral manner.

The disclosure relates to a method for slicing food products formed as product calibers using a slicing machine, comprising: arranging multiple product calibers on a feeding unit, wherein at least two of the product calibers have different lengths, feeding, by the feeding unit, the at least two product calibers along a feeding direction to a cutting unit, and slicing, by the cutting unit, the at least two product calibers into slices to form portions, wherein each portion comprises one or more slices. The method further comprises determining, based on length of at least two product calibers a first slice thickness for a first product caliber of the at least two product calibers and a second slice thickness for a second product caliber of the at least two product calibers, wherein the first product caliber before slicing has a greater length than the second product caliber, and wherein the first slice thickness is determined to be greater than the second slice thickness, so that after slicing an equal number of portions from the first product caliber and the second product caliber a length difference between the first product caliber and the second product caliber is less than before slicing. The disclosure further relates to a slicing machine.
