Abstract:
A corrugated fiberboard box assembly including a first portion including a bottom section having a pair of opposite long edges and a pair of opposite short edges with all edges being bounded by a plurality of creases, a pair of opposing side panels running along and connected to the pair of opposite long edges by two of the plurality of creases, and a pair of opposing end panels running along and connected to the pair of opposite short edges by another two of the plurality creases. The first portion being foldable to form a rectangular box with the bottom section on the bottom and the side panels and end panels both extending substantially perpendicularly upwardly away from the bottom to form side walls of the box. The box further includes a separate inner liner configured to fit within an inside of the side walls and a top configured to fit over the tops of the side walls.
Abstract:
A system and method for cutting shingles according to which a plurality of cutting blades are mounted on the outer circumference of a cutting cylinder, and the cylinder is rotated with the blades engaging the sheet while effecting relative translational movement between the cylinder and the sheet so that shingles are cut from the sheet upon one rotation of the cylinder.
Abstract:
A tailor weld blank assembly and method for making the blank assembly include providing a first metal sheet and a second metal sheet having at least one different characteristic from the first sheet. Complementary interlocking structures are provided on adjoining edges of the first and second sheets and the sheets are mechanically interlocked together by making a weld along the adjoining interlocked edges. Thereafter the permanently affixed together sheets are formed to make a formed sheet metal product. The provision of both a mechanical interlock and a weld provide a blank assembly that is strong for forming into a stamped product, and a metal product that is strong for its intended use.
Abstract:
A method and apparatus for fray-free cutting at the perimeter of an area of a textile sheet on a textile-receiving surface, including creating an anti-fray condition in the sheet along a path at the perimeter by an anti-fray instrument movable along the surface as directed by a controller based on programmed information regarding the perimeter, and cutting the sheet at the perimeter by a cutter movable along the surface as directed by the controller based on the programmed information. The anti-fray instrument is preferably an anti-fray substance applicator or, if the textile is a thermoplastic textile, a laser device configured and arranged to induce an anti-fray state therein.
Abstract:
In a method of cutting roofing shingles, multiple webs of roofing material are moved to a cutter. The webs are positioned in stacked relationship prior to the cutter. The webs have distinct portions such as tabs. The locations of the distinct portions of the moving webs are sensed by sensors. End cuts are simultaneously cut through the multiple stacked webs with the cutter to produce separate roofing shingles from the webs. The movements of the webs are controlled, based on the sensed locations of the distinct portions, so that the end cuts of the roofing shingles are positioned at predetermined locations relative to the distinct portions.
Abstract:
A method, and in particular an automatic method, of cutting parts out from sheet or plate material, the method comprising the steps of: placing templates (1, 2) having the shapes and sizes of the said parts upon said sheet or plate of material; recognizing the respective shapes, sizes, orientations, and positions of the templates on the material by means of distinctive signs characteristic of the shapes and sizes of the respective templates; and cutting out parts from said sheet or plate material along outlines defined by said templates; the method including the improvement of a further step in which any overlaps (3) between templates are detected and the lines of cut where the templates overlap are modified either by cutting along a straight line (6) interconnecting the points of intersection (4, 5) between the outlines of the overlapping templates, or by cutting along an average line (9) equidistant from the outlines of the templates between the points of intersection of the outlines of the overlapping templates, or else by cutting along the outline (7, 8) of one or other of the overlapping templates, with the type of cut being selected for each overlap zone as a function of the types of the overlapping templates and of the portions of template outlines concerned, said selections being suitable for storage in a list of possible types of cut, which list may be consulted immediately after detecting and identifying a given overlap. These overlap operations may be performed by computer.
Abstract:
In a method for simultaneously cutting three continuous double-comb components from a metal strip the strip is moved forward stepwise. At each stop, a row of notches is made along each edge to form teeth and a row of crosses is removed from its central part, the crosses being made up of two portions of the central part and two teeth facing notches and separated therefrom by a portion of the central part. After the teeth have been bent, the comb-shaped components can be used to reinforce rubber packing or linings, more particularly in the car industry.
Abstract:
A puzzle formed from a block including several variously configured, interlocking unitary pieces which are slideable into and out of the block for assembly and disassembly. The pieces assemble into two intersecting cylinders within the block including a central piece which forms a part of both cylinders. The preferred method of forming the puzzle comprises cutting the cylinders by causing the instrument used for cutting to enter and exit the block along a single line for each cylinder.

1,140,498. Joint-making packing. AMERICAN AIR FILTER CO. Inc. 25 Oct., 1967 [25 Oct., 1966], No. 48561/67. Heading F2B. An endless gasket is made from sheet material 2 by forming in the sheet longitudinally extending sections 3, 7 and 8 in compact adjacent relationship with each section integrally joined to an adjacent section through a corner 11, 13 on the extremity of one section joined to the other section with the remainder of the extremity being free; removing the sections from the sheet; and pivotally expanding them about the joined corners so that the free extremities abut the adjacent sections to form the gasket. The sheet 2 may be of natural or synthetic rubber or plastics material. In a modification, Figs. 3 and 4 (not shown), an annular gasket is formed by four segments (32) integrally connected at adjacent corners (35, 36). A dovetail arrangement (37, 38, Fig. 5) may be provided at the junctions.
