Abstract: An apparatus for dividing strip material, in particular strip-shaped scrap resulting from edge-trimming of rolled strip and metal sheet, comprises at least one pair of mutually co-operating cutters (18, 18a), between which the strip material (14) is fed and which are arranged to penetrate the strip material from mutually opposite sides. The two cutters in each co-operating pair are mutually substantially parallel at the moment of their penetration into the strip material. The one cutter (18) in each pair is arranged to engage the strip material slightly in front of the second cutter (18a), as seen in the direction of movement of the strip material, and then to move away from the second cutter in the direction of movement of the strip material, such that the part of strip material located in front of the cutters is separated from the remainder of the strip material by a combined cutting and tearing operation.

Abstract: Method and apparatus for partitioning and/or shaping a fibrous batt by gripping the batt along adjacent lines with resilient means gripping one surface and non-resilient means gripping the opposite surface and displacing said lines with respect to each other to separate the batt without compacting the parted edges of the batt.

Abstract: A catalyst strand sizer is described which produces catalyst pellets of uniform preselected length without producing an excessive amount of fines. The catalyst sizer comprises two fixed rotatable rolls wherein one roll has a compressible surface and the other roll is covered with a wire mesh of selected dimensions whereby when the catalyst strand extrudate is passed between said rolls, the strands are broken into catalyst pellets of preselected length.

Abstract: Pulses from a motor-driven roto pulser, e.g., primary pulses, and from a roto pulser powered by a moving ribbon, e.g., secondary pulses, are (1) compared to determine if the ribbon is continuous and (2) used to actuate ribbon cross scoring and snapping equipment. When the secondary pulse count exceeds the primary pulse count for a given ribbon displacement by more than a predetermined amount, indications are that a ribbon break has occurred and the scoring and snapping equipment is actuated by the pulses from the ribbon powered roto pulser. When the difference between the secondary pulse count and primary pulse count is less than the predetermined amount, indications are that the ribbon is continuous and the equipment is actuated by pulses from the motor-driven roto pulser.

Abstract: A burster for separating successive sheets of paper from a continuous web of paper has at least one output or draw roller having a larger diameter than the input or feed rollers with all of these rollers rotated at the same r.p.m. and a simple belt drive mounted on a pivotal double link with a one-to-one ratio provides for driving one set of rollers from the other set with an adjustable distance between sets of rollers.

Abstract: Rectangularly shaped snapstrates are separated into substrates along kerfs that are parallel to edges thereof by belt and roller flexure forces produced by two belts that are caused to be contiguous over the suspended length of the upper belt by a pressure roller forcing the two belts together at an intermediate point between roller supports for the belts. This produces oppositely facing curvatures in the belts at spaced apart transverse lines thereon which flex snapstrates in opposite directions with a flexure force which is sufficient to separate snapstrates on the lower belt with kerfs facing in the right direction and which is not sufficient to separate snapstrates there with kerfs facing in the wrong direction. In an alternate embodiment, the peripheries of rollers are tapered in vertical sections for separating snapstrates along kerfs oriented at right angles. In a further embodiment, only a single belt with a pressure roller pressing down on it is employed to separate snapstrates.

Abstract: A method of severing useful lengths connected together by small fillets in a sheet of paper, pasteboard or the like, comprises applying the sheets on to a substantially non-flexible support having a contact surface of a first coefficient of friction, and then exerting on adjacent useful lengths, through forces which act in opposite directions tangentially on said adjacent useful lengths with a contact pressure by way of a second coefficient of friction exceeding the value of said first coefficient of friction, a splaying movement sufficient to destroy the fillets. Apparatus for carrying out the method may comprise a press, pressure fingers disposed at both sides of the longitudinal axis of said press, and contact surfaces having said comparatively high second coefficient of friction and at the free ends of said pressure fingers, said contact surfaces being intended for application to the useful lengths to be severed.

Abstract: An extrudate cutting device comprising(a) a frame means,(b) attachment means mounted on said frame means for attachment thereof to the extrusion end of an extruder,(c) second attachment means mounted on said frame means and adapted to receive a rotatable elongated cutting means and(d) elongated cutting means rotatably mounted on said second attachment means and a method of cutting extrudate into substantially identically sized sections, are disclosed.

Abstract: Flat glass advancing along a conveyor in the form of a continuous ribbon or individual sheets, is broken into cullet by applying breaking loads to the glass which put breaking stresses into the glass simultaneously about two axes which are substantially orthogonal to one another.

Abstract: A positive acting apparatus or machine is disclosed having an upper, downwardly movable blade assembly and a lower fixed position opposed blade assembly for cutting-off selected lengths of a resin or plastic sheetlike material. Fluid motors are employed for raising and lowering the upper blade assembly, and rack and gear means is provided for assuring that both end portions of the assembly move in exact synchronism. The upper blade is aligned with and operated on the same vertical plane as the lower blade, and means is provided for stopping downward movement of the upper blade when it approaches close adjacency with but before it engages the lower blade. Electrical heating elements extend longitudinally along the blade assemblies and are energized to maintain the blades at a raised temperature during their applicatin to the material.

Abstract: A forms bursting apparatus having a brake bar which grips a document to be separated, transversely holding the document during the bursting operation. A bursting bar assembly forces the leading document portion against a rotating burster roll. A bursting bar, which grips the document, is swingably mounted for rotation with the bursting roll during the bursting.

Abstract: Bags from a roll of polyethylene bags are fed through a braking device and thence past spreading devices and a floating hook support, whereupon are engaged sequentially the hooks of hangers upon which garments or the like are supported. The bags are provided with indicia which are detected by a detecting device to actuate the braking device so that the bags may be readily torn off before they seat on the respective garments being packaged. Provision is made for adjustments of the braking time so that the brake automatically releases after a fixed period of time thereby facilitating a drawing of the bags from the source for sequential bagging operations.
