摘要:
A method of cutting a continuous hollow tubular member having a fully expanded configuration with an outer diameter D, includes the steps of feeding the continuous hollow tubular member in the fully expanded configuration to a cutting station, cutting the continuous hollow tubular member into a plurality of hollow tubular members, each of which has a first flattened end and expanding the first flattened end of the plurality of hollow tubular members to the fully expanded configuration such that the first end of the plurality of hollow tubular members has an outer diameter D.

A variable interference anvil and knife combination is provided to selectively sever elastics in a laminate and preferably not sever the nonwoven portions of the laminate. The distance between the anvil and the knife can be programmatically altered to provide for smaller or larger gaps as processing speeds are changed.

Apparatus for cutting source material in the form of a thin moving web includes a rotating cutting cylinder having an outwardly extending mounted blade and a closely spaced support member. Disposed between the blade-bearing lateral surface of the cutting cylinder and the support member, and in contact with the support member, is a movable, generally flat anvil strip adapted to engage, position and support the thin web to allow the rotating blade to sever the web material. The anvil strip is displaced in a reciprocating manner between a retracted position at the beginning of the blade's cutting stroke and an activated position at the end of the cutting stroke, prior to return of the anvil strip to its initial retracted position. The combination of a leaf spring and a ball bearing arrangement attached to each opposed end of the anvil strip permits this repetitive, reciprocating motion, where each leaf spring and ball bearing combination is of reduced mass and traverses a contoured path to allow for: (1) higher anvil strip reciprocating and web processing rates; (2) reduced blade wear, anvil strip oscillation amplitude, and inter-component friction; and (3) accommodating jamming of the machine by the severed web material without damage to the machine and with reduced operation interruptions.

An input conveyor, output conveyor, and knife assembly with a blade between the input and output conveyors all reciprocate back and forth as a blade moves perpendicular to the conveyors to cut portioned sized of product, such as ground meat. The cut cycle allows the product feed to keep moving in a continuous manner on conveyors. For ground meat, this system can allow production rates of 150 pieces or more per minute per conveyor line and can improve the accuracy of portioning. The blade is actuated by a profiled cam set that pulls the blade down, and then returns it with a spring to an upper position. The knife assembly can accelerate just after cutting to reduce the potential for sticking to the cut product.

A roll includes a succession of sheets of single-use absorbent paper, the succession of sheets includes a first sheet partially defined by a first line of perforations and a first cut arrangement partially defined by a first cut, a second cut, and a connecting region arranged between the first cut and the second cut and a second sheet partially defined by the first cut arrangement, and a second line of perforations.
摘要:
An adjustable pouch machine comprises a vertical sealer module forms transverse seals between two plies of a pouch web to partially define a plurality of pouches. Rollers selectively tension and relax the web on the vertically oriented wheel, allowing them to drop away from heated lands on emergency and cycle stops. A filler wheel has a plurality of adjustable gripper units mounted directly thereon for transporting independent separate pouches cut from the pouch web. An adjustable knife is selectively provided with changeable knife hub sets to handle a variety of pouch sizes where a filler wheel alternately first fills and seals pouches in a train. Gear linkage accommodates variation in distance between hubs of different sets. Various embodiments, apparatus and methods are described.

A machine for cutting a continuously extruded tube into segments of lesser and predetermined length, comprising: —means (33) for actuating sliding means (3) that are movable along a guide (30) parallel to a direction (20) of advance; said sliding means (3) comprising a first and a second station (31, 32) for cutting the tube which in turn comprise respectively a first and a second shearing cutter (311, 312). To the first shearing cutter (311) is associated a first cutting plane (310) transverse to the direction (20) of advance of the tube, to the second shearing cutter (312) is associated a second cutting plane (320) that is transverse to the direction (20) of advance of the tube and distal from the first cutting plane (310);—means for measuring the relative displacement between said tube and said first and second cutting plane (310, 320) along the direction (20) of advance of the tube;—control means commanding said actuating means (33) of said sliding means (3) according to the desired length of the segments produced by the machine (1) and according to the information provided by said measuring means.

摘要:
A tissue harvesting method and device for obtaining micrograft tissue particles within the size range of 50-1500 microns, and more preferably 500-1000 microns, and most preferably 600 microns. The particles may be processed after a piece of donor tissue has been excised from the donor site, or processed into the desired size directly at the donor site, and thereafter excised. Cutters having blades or cutting edges spaced in the range of 50-1500 microns are utilized to obtain particles within the desired size range. An elastomer is positioned between the cutting edges to push the excised particles out of the blades for ease of use.
