  • Patent number: 9511502
    Abstract: An apparatus for cutting a sheet stack is provided. The sheet stack is composed of a plurality of sheets. The apparatus includes a cutting blade having a plate form and having a cutting edge at one side extending along a cutting width direction. The cutting blade has at the one side: a plurality of projecting blade portions having ridge lines forming edge lines capable of thrusting and sawing cutting, the projecting blade portions projecting in a cutting direction; and a straight bottom portion between adjacent projecting blade portions. Cutting of the sheet stack is performed by applying a load to the cutting blade in the cutting direction, and by reciprocating the cutting blade along the cutting width direction.

  • Patent number: 8864006
    Abstract: A container puncturing device for efficiently and safely emptying the contents of a container into a storage tank or other structure. The container puncturing device generally includes a cross bar having a pair of tank attachment assemblies, a pair of bucket attachment assemblies and a puncturing member secured thereto. The bucket attachment assemblies are adapted to allow the present invention to be lifted and moved by a loader bucket such as one attached to a skid steer loader. The tank attachment assemblies are utilized to secure the present invention to the upper end of a tank. When a container is lowered onto the puncturing member, any particulate materials stored therein will be dispensed into the tank through the punctured opening. The present invention may then be lifted off and away from the tank through use of the bucket attachment assemblies and a loader bucket.

  • Publication number: 20140305272
    Abstract: An apparatus for creating perforations in wrapping film uses a component that contains a plurality of needle points (or other piercing features) formed along a free-wheeling support bar. The bar is positioned to contact the wrapping film while it is being unrolled and is in a ‘tensioned’ state (in some embodiments, immediately prior to contacting the element to be wrapped). The free-wheeling perforation apparatus contacts a mechanized (driven) film roller such that the exposed needle points rotate against the driven roller and make the perforations in the film as it travels over the film roller. As long as the film roller is formed of a pliable material, the needles will pierce the film and create the desired perforations. The size and placement of needles can be adjusted to provide the required pattern of perforations, as well as dictate the size of the actual perforations.

    Abstract: A hydraulically-operated ripper tool mounted as an attachment on a hydraulic arm of a carrier or excavator is used for demolition of large metal walled structures such as storage tanks in a very short time. The ripper tool has a sharp point for punching entry holes into the tank walls, so that no torch cutting of entry holes needs to be used, particularly where there might be volatile residues left in the tank. The ripper tool has a concave, sharp inner edge and is operated by the hydraulic arm in reciprocation so as to provide a shearing force to cut quickly through metal walls in “can-opener” fashion. The ripper tool facilitates making long vertical cuts into the tank wall from top to bottom, so that a series of vertical cuts can be made to weaken a side of the tank and allow the top of the tank structure to be brought down.

Piercing needles are arranged on the second shaft, spaced from each other in a circumferential direction, projecting radially outwards, rotatable about a second axis, and extendable and retractable relative to an outer surface via holes in the outer tube. A needle restraining member, rotatably supported on the second shaft, transmits torque to the piercing needles when driven for rotation. The first plurality of needles rotate in unison, as do the second plurality of needles and are fixedly connected to support members; thus, protecting the needles from unreasonable force and preventing undesirable enlargement of pinholes and deformation of the rubber sheet. Further, when the needles are advanced into the rubber sheet and retraced therefrom, enlargement of the rubber sheet pinholes can be prevented.

  • Patent number: 6935199
    Abstract: A headspace gas sampling and venting method utilizes a vent port and a sampling port which are punched through the lid of a drum containing hazardous materials, such as transuranic waste. In accordance with the system, a punch having a hollow passage therethrough, which passage has a filter element therein is first inserted through the lid using a pneumatic gun. A second punch, similar to the first punch, but having a passage with a septa seal therein is thereafter inserted through the lid with the pneumatic gun. Headspace gas beneath the lid is then sampled with a needle inserted through the septa seal. Both the venting port and sampling port are configured with detachable punch points which pass through the lid and are then released from the venting and sampling ports so as to open ends of the passages therethrough for communication with the headspace.

  • Patent number: 6860012
    Abstract: A method for forming elastic ventilation cushion comprises the steps of arranging a plurality of needle seats at two banks, an upper bank and a lower bank, and a straight gap is formed between the upper bank and the lower bank, wherein one edge of each needle seat near the other bank is mounted with a plurality of slender needles, wherein each distal end of the needles is folded as a distal folded section; passing an elastic cushion through the gap; and moving the needle seats at the upper and lower banks so that the length of the gap is enlarged or reduced, thereby, the needles on the needle seats will pierce the elastic cushion and the distal folded section will tear surfaces of the elastic cushion to form a plurality of elastic ventilation slits on the elastic cushion. Moreover, the needle seats can be replaced by needle rollers.

  • Publication number: 20030226431
    Abstract: A perforation forming apparatus for a web fed paper processor generally comprising a perforator cylinder and an anvil cylinder. The rotatable perforator has at least a blade protruding radially from the cylinder. The rotatable anvil cylinder is adjacent the perforator cylinder and is contiguously engageable therewith. One of the perforator cylinder and the anvil cylinder is supported by eccentric bearing assemblies, comprising fluid cooled bearings eccentrically mounted in bearing housings and therefore adapted for rotation such that the eccentrically mounted cylinder can be pivotally displaced between a first and second position. Whereby pivoting to the second position during operation temporarily suspends perforation of the paper web, and returning to the first position during operation resumes perforation of the paper web.

  • Publication number: 20030145708
    Abstract: The invention is a method and apparatus for making conduit for use in leaching systems, and the conduit produced thereby. The conduit has apertures created during its formation. The apertures are not cut from the material of the conduit. The material that is perforated is “rolled”, and made a part of the inner surface of the conduit. Included is at least one perforator that is actuatable. The conduit-forming material being perforated (typically a plastic-type material) is semi-molten, as during formation of the conduit, or after formation of the conduit by heating the perforator, thereby causing the conduit-forming material to be rolled rather than cut in creating a perforation. The apparatus has at least one actuatable perforator or at least one multi-tipped sequentially actuatable perforator located in at least one of a plurality of conduit-forming molds.

  • Publication number: 20030121380
    Abstract: Improved aperturing of a web can be obtained by providing pins with an extended tapered section that is substantially convex in shape. When the tapered section is longer than the penetration depth of the pins into the receiving recesses of a female roll, frictional forces in the nip between layers are reduced. Pins with extended tapered sections can be used in devices for producing apertured composite web assemblies comprising sections of absorbent matter attached to a nonwoven web or other carrier layer.
