The present invention relates to an apparatus and a process for cutting a substrate wherein the apparatus comprises first and second cutting element and wherein the first and second cutting elements are rotatable about the axis of rotation at different circumferential speeds.

An apparatus for manufacturing an elastic composite structure for an absorbent sanitary product includes an anvil with weld pattern comprising at least one anchoring region and at least one deactivating region. The anchoring region includes anchoring welds that form anchoring bonds that fuse facing web layers and anchor elastic thread(s) in position relative to the facing web layers. The deactivating region includes a break bar constructed to sever the thread(s). A method of manufacturing the elastic composite structure includes positioning a tensioned elastic thread between web layers, fusing the web layers to form an anchored zone that includes anchoring bonds that fuse the web layers and anchor the tensioned elastic thread therebetween, and cutting the thread to form a deactivated zone between adjacent portions of the anchored zone that is free of tensioned threads. The method further includes fusing the web layers within the deactivated zone.

An apparatus and method for forming a plurality of individually folded and rolled wipe products, which allows for multiple individually folded and rolled wipe products to be processed concurrently, and which maintains moisture in the wipe product during manufacturing.

The lubrication device delivers a lubricant to the perforating device which provides intermittently spaced cuts to a moving web, also referred to as perforations. The lubrication device includes a retaining member, a plenum, and a comb having a plurality of comb channels. The plenum and the plurality of comb channels are in fluid communication with one another and deliver a lubricant to the perforating device. Lubrication of the perforating device in this manner may improve knife life, perforation quality and web handling.

The device includes a hollow cutting roller with a blade attached to the outer surface of the hollow roller. A stationary shaft is also provided, arranged inside the hollow roller and coaxial therewith. The stationary shaft is connected to a supporting structure and the hollow roller is rotatably supported onto the stationary shaft). A motor drive is provided to rotate the hollow roller around the stationary shaft. The hollow roller is supported onto the stationary shaft by at least a hydrostatic bearing arranged in an intermediate position between the ends of the stationary shaft.

A cutter roll and an anvil roll, with which it is possible to control deformation in the axial direction, and a rotary cutter having the same. A roll 101, 210 for a rotary cutter includes: a barrel portion having a circumferential surface and a pair of end surfaces located respectively at opposite ends of the circumferential surface; a pair of first depressions 113, 213 having a ring shape or a cylindrical shape and located respectively at the pair of end surfaces of the barrel portion, the pair of first depressions each having a depth direction that is parallel to an axis of the barrel portion; a pair of first bearings 152, 252 located respectively in the pair of first depressions and being in contact with outer walls of the first depressions; and a pair of first bearing boxes 156 located on an outside of the pair of first depressions and having support portions 151b, 251b to be in contact with a support frame or a pressure mechanism, the pair of first bearing boxes supporting the respective bearings.

Cutting systems and methods capable of performing a variable cutting operation on a continuous web. The system includes a first cutting apparatus configured to receive the web and perform a cutting operation thereon to produce unfinished documents, and a second cutting apparatus configured to subsequently perform a trim cutting operation thereon to produce finished documents of selectively defined finished lengths, wherein the second cutting apparatus has a feed direction that is perpendicular to a feed direction of the first cutting apparatus. The system includes a conveyor system configured to receive the unfinished documents from the first cutting apparatus, arrange the unfinished documents into a stream of shingled documents traveling in the feed direction of the first cutting apparatus, and turn the unfinished documents at a right angle to travel in the feed direction of the second cutting apparatus without changing their orientation.

An ultrasound-induced positioning type puncture assembly and a sleeve type small needle knife are provided. The small needle knife includes a cutting assembly and a puncture assembly. The puncture assembly includes a puncture needle core and a puncture sleeve; an annular groove facing an ultrasound equipment probe is formed in an outer wall of the puncture sleeve along a circumferential direction; and a cross section of the annular groove is of lug-shaped.

The invention relates to a cutting device and method for cutting prefabricated transverse seal seams of a tube composed of plastic film and filled with food, particularly soft cheese, wherein each transverse seal seam of the continuously supplied film tube to be processed separates one portion of the food from the next portion. The device comprises a rotating knife holder provided with at least one knife blade 22, and wherein the knife blade 22 acts on a counter bearing 4 when cutting a transverse seal seam, wherein said knife holder has a heating element for heating the knife blade 22 in a targeted fashion.
