A deagglomerator for use in resizing masses of cells. The deagglomerator may include a plurality of apertures defined by a plurality of front and back edges. The masses of cells may be passed through the plurality of apertures from the front to the back, and from the back to the front, repeatedly. The deagglomerator may also include a plurality of blades that may aid in the deagglomeration of the cell masses. The deagglomerator may be configured between two syringes so that the tissue may be passed back and forth from the first syringe through the device to the second syringe, and then back again from the second syringe through the device and to the first syringe. In this way, the masses of cells may be properly deagglomerated.

The invention relates to a circular knife device (10) for cutting to size sheet-like materials, in particular paperboard and/or textile materials, in particular cover boards and/or covering materials, wherein the circular knife device (10) defines a cutting plane in which the sheet-like materials are arranged and are moved in a transport direction (14), having at least one circular knife (46) and an associated circular knife axis, wherein the circular knife (46) is rotatable about the circular knife axis, wherein the at least one circular knife (46) is movable parallel to the cutting plane and perpendicularly to the transport direction (14) with the result that a blank width of the sheet-like materials is settable in a variable manner, wherein the at least one circular knife (46) is mounted so as to be pivotable about a pivot axis (52) arranged substantially perpendicular to the cutting plane such that cuts at an angle to the transport direction (14) and curved cuts of the sheet-like materials are able to be executed.

A cutting device and corresponding method for cutting a relatively rigid material), such as for example paper, cardboard, plastic material, composite or other. The cutting device includes a first cutting disc sharpened along its peripheral edge and rotating around its a first axis of rotation. A second cutting disc, also sharpened along its peripheral edge (and rotating around a first axis of rotation (X3), is disposed in front of the first cutting disc with respect to the material and is co-planar with the first cutting disc (14).

A printed unit block aligning device includes a supporting element and an alignment transfer rail. The supporting element is opened and closed between a supporting position and a releasing position. The alignment transfer rail receives the group of the printed unit blocks dropped in response to move of the supporting element to the releasing position, aligns the printed unit blocks in each line unit block in a vertical direction, and feeds the printed unit blocks vertically at a constant speed using alignment transferring element. An electrical controlling element is provided that electrically controls timing of dropping the printed unit blocks from the supporting element onto the alignment transfer rail. While a speed of transfer of the horizontal feeding and transferring element are uniform for any imposition structure, the electrical controlling element controls timing of dropping the printed unit blocks in a manner that depends on the numbers of layers in each vertical line in different imposition structures.

A mechanism and a method for slitting silicone membranes using automated slitting blades is presented. The pattern of slits in the membrane can be adjusted by using a cutting cylinder comprised of a plurality of circular cutting gears assembled in parallel.

The cutting cylinder is of indefinite length, but in the preferred embodiment is approximately 15″ long and 3″ in diameter. The silicone membrane can range in thickness from 0.005″ to 0.01″ inch.

An arrangement in a warehouse and a method for forming narrow rolls are disclosed. The narrow rolls are formed from a jumbo reel. At least two slitting machines are used for forming the narrow rolls. The jumbo reel has an axial direction when positioned on the slitting machine. The narrow rolls are transferred to the warehouse in the axial direction. The at least two slitting machines are positioned overlapping.

A slit-cutting device includes a first holder, a second holder, a first contactable member a second contactable member, and a protrusion member. The first holder includes a medium faceable area and a first contactable member. The second holder holds a blade and includes a second contactable member. A cutting edge of the blade may cut a medium between the first holder and the blade. The first contactable member and the second contactable member contact each other and defined a closest approach distance between the cutting edge and the first holder. The closest approach distance is longer than zero and below a thickness of the medium. The protrusion member protrudes more than the closest approach distance from a part of the medium faceable area. The cutting edge may make a cut line includes at least a part of a slit-cut and a full-cut in a cutting edge direction in the medium.
