Patent number: 5486133Abstract: A toothed timing belt is produced from a belt blank utilizing an apparatus having a belt blank fixturing device for supporting the belt blank for selective indexable rotation about a first axis and a toothed grinding wheel rotatable about a second transverse axis and supported for movement across the width of the belt blank in a direction parallel to the first axis for cutting a series of circumferentially spaced transverse teeth into the belt blank. The belt blank is indexed with each pass of the grinding wheel until the entire belt has been provided with teeth. The toothed belt blank may then be severed about its periphery to provide a plurality of discrete timing belt members.Type: GrantFiled: May 31, 1994Date of Patent: January 23, 1996Inventor: Jerry Russell

Patent number: 5405486Abstract: Disclosed is a method and apparatus for forming a transdermal drug delivery device from a multilayer web comprised of a backing layer, a drug-containing pressure sensitive adhesive layer, and a release layer or liner in which cutting is progressively achieved along a line coplanar with the axes of a cutting roller and anvil roller counter-rotating in proximity to each other. In one embodiment, cutting is achieved completely through the web about the periphery of the transdermal drug delivery device, while simultaneously achieving a scoring only of the release liner without penetration of the pressure sensitive adhesive layer or backing layer. In an alternate embodiment there are two arrangements of rollers. A first arrangement has a cutting edge for scoring the web. After scoring, the web is passed to a second arrangement for cutting through the web to result in the transdermal drug delivery device.Type: GrantFiled: June 21, 1993Date of Patent: April 11, 1995Assignee: Noven Pharmaceuticals, Inc.Inventors: Steven Sablotsky, Ronald E.

Patent number: 5224409Abstract: An apparatus for producing helical slices of an object, such as a potato. The apparatus includes a rotatably mounted knife assembly having one or more sets of knife blades arranged in a spiral pattern. Each set of knife blades produces a set of helically shaped potato slices. The spiral arrangement of each blade set reduces the torque needed to slice an object using the knife assembly. In a preferred embodiment, the inventive apparatus includes two sets of slicing blades, for producing two sets of intertwined helical product slices. A curved separator tube, which extends downward from the slicing blade area, disentangles the pair of intertwined slices having the smallest radius, as the blade assembly and the separator tube rotates as a unit.Type: GrantFiled: June 27, 1991Date of Patent: July 6, 1993Assignee: Ashlock CompanyInventors: Frederick J. Cimperman, Klaus Silbermann

Patent number: 5211711Abstract: A package of substantially identical containers, such as beverage cans, and a carrier and a method of making such packages are disclosed. The carrier has band segments defining container-receiving apertures and additional apertures. The carrier is applied so that the containers are received in the container-receiving apertures and so that the band segments engage cylindrical side walls of the containers. Among the band segments, terminal cross segments define opposite ends of the carrier and medial cross segments separate the container-receiving apertures in each longitudinal row. Each medial cross segment is severed partially, for a substantial distance along its transverse midline, from one of the opposite edges of the carrier, toward one of the additional apertures and has at least one secondary slit extending transversely between the transverse midline and one of the container-receiving apertures.Type: GrantFiled: May 29, 1992Date of Patent: May 18, 1993Assignee: Illinois Tool Works Inc.Inventor: Leslie S. Marco

Patent number: 5197681Abstract: A slicing/shaving machine particularly adapted for high speed slicing/shaving or food products in which at least one slicing/shaving blade defines a slicing/shaving edge of a generally arcuate configuration. The blade is carried by a slicing/shaving drum which is rotated about an axis to impart a circular path of travel to the slicing/shaving edge disposed at an angle other than parallel thereto. The product is fed/guided generally radially toward the slicing/shaving edge and is sliced/shaved thereby along the circular path in a continuous high speed fashion.Type: GrantFiled: December 3, 1990Date of Patent: March 30, 1993Assignee: Beltec InternationalInventor: Benno E. Liebermann

Patent number: 5176613Abstract: A process and an apparatus for preventing a packaging material which is being die-cut and scored from developing cracks. A crack-reducing sheet material (17) is positioned between the cutting/scoring tools (9, 13) and the packaging material (5) to absorb impact energy from said tools and relieve the packaging material of crackproducing forces in the direction of its plane.Type: GrantFiled: July 5, 1991Date of Patent: January 5, 1993Inventors: Soren Cavlin, Birger Edholm

Patent number: 5159869Abstract: A cutting station comprising a bed; a work surface supported on the bed; a carriage traveling along the longitudinal axis of the bed by virtue of a first motor; two cutting members connected to two second motors; and a structure supporting the cutting members and second motors, and designed to travel, by virtue of actuators, along vertical slideways supported on the carriage, and to be carried by the carriage during traversing of the same. The bed comprises two fixed parallel beams supporting the work surface, and a first of which also supports two horizontal slideways for supporting and guiding the carriage. The center of gravity of the second motors lies within the space defined between the horizontal slideways.Type: GrantFiled: October 17, 1990Date of Patent: November 3, 1992Assignee: Selco S.r.l.Inventor: Renzo Tagliaferri
