Patent number: 5125302Abstract: A machine is described for perforating webs of material, such as toilet paper. The machine includes a cylinder (17) mounted on the frame of the machine and around which cylinder the web is carried as the web passes through the machine. The cylinder has a plurality of blades, one edge of each extending beyond the surface of the cylinder and parallel to the axis of the cylinder. A support (21) for a cooperating blade (33) is pivotally mounted on the machine in a manner which permits the cooperating blade (33) to move toward and away from the blades in the cylinder (17). The cooperating blade (33) extends at an angle to the axis of the cylinder and consists of a plurality of segments, each of which is supported in a block (25) which fits into seats in the support. The seats extend in a line parallel to the cylinder axis.Type: GrantFiled: December 24, 1990Date of Patent: June 30, 1992Assignee: Fabio Perini S.p.A.Inventor: Guglielmo Biagiotti

Patent number: 4979418Abstract: A method and apparatus are disclosed for efficiently cutting food items, such as potatoes, into helical strips. The food items are provided seriatim to the cutting assembly from a conveyor system fed by a trough shaker or other singulator device. Food items on the conveyor are aligned longitudinally and are then impaled on small spikes protruding from the conveyor so that they maintain the longitudinal orientation during their travel to a feed roller portion of the system. The feed rollers firmly grip the food items by their peripheries and advance them into the rotary cutting assembly. This assembly includes a helically shaped cutting member defining at a leading edge thereof a slicing blade and supporting on its front surface a plurality of perpendicularly extending scoring blades. The helically shaped cutting member is mounted at its periphery by being threadedly received in a helical thread cut in an annular holder.Type: GrantFiled: November 12, 1987Date of Patent: December 25, 1990Assignee: Lamb-Weston, Inc.Inventors: Darrell L. Covert, Gary D. Cuddeford, Kenneth J. Stanley, John C. Julian

Patent number: 4926726Abstract: A method and apparatus are disclosed for efficiently cutting food items, such as potatoes, into helical strips. The food items are provided seriatim to a cutter head assembly from a conveyor system. Food items on the conveyor system are aligned longitudinally and fed to the cutter head assembly. The cutter head assembly includes a cylindrical sleeve or tube having an open discharge end and an opposed cutting end to which a cutting member is attached. The sleeve is supportively carried by a cylindrical jacket having a pair of outer flanged members, a central drive-belt engaging member and fasteners coupling the outer members together to secure the central member therebetween. The sleeve is secured coaxially within the jacket by fasteners and the entire assembly rotated by a drive belt engaging the central member. The entire assembly is supported by idler rollers which ride in a circumferential track formed by the jacket and by thrust rollers which engage the discharge end of the cutter head assembly.Type: GrantFiled: January 3, 1989Date of Patent: May 22, 1990Assignee: Lamb-Weston, Inc.Inventor: John C.

Patent number: 4911047Abstract: A synchronous rotary cross-cutter is disclosed with two oppositely rotated, axially parallel cutting rotors that support cooperating, helically extending knife blades with cutting edges situated in a cylindrical envelope. The axes of these cutting edges run at an angle, corresponding to the inclination of the helix, with respect to the direction of advancement of the material web being cut. To accommodate different cutting lengths without the need for a controllable irregular drive for this purpose, the axial distance of the cutting rotors from the material web is variable and the knives are mounted on a flat blade holder that runs substantially tangentially in the rotor cross section and is slightly flexible. The knife blade holder, supported by a series of individually adjustable supporting elements, can be given a slight flexure with a radial adjustment, so as to assure that the position of the cutting edge of the knife remains within in the cylindrical envelope.Type: GrantFiled: May 26, 1988Date of Patent: March 27, 1990Assignee: Valmet-Strecker GmbHInventors: Hans Hornung, Bernd Fuchs, Eduard Voltz

Patent number: RE38149Abstract: A cutter for cutting helical vegetable strips comprising a circular disk-like plate having an upstream surface and an axis of rotation. The cutter has a knife blade extending radially from the axis of rotation, the blade edge being axially displaced from the upstream surface. The cutter also includes a plurality of slitter blades spaced apart and located at different distances from the axis of rotation and extending substantially perpendicular to the upstream surface. The slitter blades have different lengths and, therefore, extend to different heights above the upstream surface.Type: GrantFiled: May 13, 1999Date of Patent: June 24, 2003Assignee: McCain Foods LimitedInventors: Jocelyn A.
