The shoulder/nozzles are made and oriented with the shoulder opening to be facing the laminate film. The film is fed to a station that forms the nozzle aperture, die cuts the laminate film to fit into the shoulder of the shoulder/nozzle, and inserts this laminate film into the shoulder/nozzle. The laminate film can be heat bonded to the shoulder nozzle at this station or in a subsequent sealing station. After the shoulder/nozzle leaves the station that forms and inserts the laminate film into the shoulder/nozzle there can be a detection station to determine if the laminate film is properly aligned in the shoulder/nozzle. There also can be a detection station after a subsequent sealing station. Shoulder/nozzles with sealed laminate film liner are then sent to tube making.

  • Patent number: 8029428
    Abstract: A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a single sealing zone, and a weakening zone disposed within the single sealing zone. The single sealing zone may be a heated perforator, and may include a heating wire. The heating wire may be an NiCr wire stitched into the heater, and be disposed on a cap or on the seal bar. The weakening zone may create a line of weakness that is uniform or varies in intensity. The sealing zone may include temperature zones, cartridge heaters, cooling air, or heated air, or a source of ultrasonic, microwave or radiative energy.

  • Publication number: 20110220272
    Abstract: A coupled portion of mutual laminate films sufficiently contributes to the formation of a packaging bag in that the coupled portion itself has excellent air tightness and liquid tightness. The tensile strength required for the laminate film is given to the coupled portion, whereby a temporary stop of a packaging apparatus is useless when a connecting portion of the laminate film is passed through the apparatus, thereby enhancing the operation efficiency and improving the yield of the material. Oriented base film layers are joined in a mitre form at the coupled portion between a rear end portion and a front end portion of laminate films comprising oriented base film layers and sealant layers.

  • Patent number: 7959754
    Abstract: An appliance for sealing elastic hoses with a sleeve, which is plastically deformable and slipped onto the hose, has two jaws which are movable towards and away from each other. One jaw has two straight bars which project towards the other jaw and extend transversely of the sleeve to make two transverse indentations in the sleeve and the hose when the jaws are moving towards each other. The same jaw has a cutting edge which projects towards the other jaw and is directed transversely of the sleeve, the cutting edge making a substantially transverse cutting indication in the sleeve and the hose when the jaws are moving towards each other.

  • Patent number: 7942996
    Abstract: An end face of an intermediate layer of a multilayer structure is stably covered by surface resin layers at a time of cutting the multilayer structure. A cutting method of the multilayer structure includes the steps of: compressing and deforming the multilayer structure, while extending respective layers of the multilayer structure to provide a thin thickness portion, so that an upper layer bites into a lower layer by pushing a push cutter, by a predetermined amount, into the multilayer structure supported by a cutter receiving portion, in a fused state of at least one of the resin layers forming the multilayer structure; and push-cutting the compressed thin thickness portion S till the push cutter abuts against the cutter receiving portion so as to converge an intermediate layer and surface resin layers of the multilayer structure to the abutting portion A of the push cutter and the cutter receiving portion.

  • Patent number: 7896047
    Abstract: A grinding unit grinds an annular convex portion formed at an outer periphery of a back face of a wafer such that the wafer has a uniform thickness. After such process, a robot arm of a transport unit transports the wafer to an inspection unit for inspecting occurrence of damage at the wafer. Then, the robot arm transports the wafer without damage to a mount frame preparation unit. Herein, the wafer is joined to a ring frame through a dicing tape, and then a protective tape is separated from a front face of the wafer. Thus, a mount frame is prepared.

  • Patent number: 7833367
    Abstract: A strip-shaped supporting adhesive tape is joined to a ring frame, and then is stuck with a cutter blade such that the cutter blade penetrates the adhesive tape. In a state where a cutting edge of the cutter blade is brought into contact with a tape joined side of the ring frame, thereafter, the adhesive tape is cut along a contour of the ring frame while electric current is fed to each of the cutter blade and the ring frame. Herein, a sensor monitors a conduction status in real time.

  • Patent number: 7810540
    Abstract: A hand-held electric sealer with dual heads includes a seat, a sealing module, a press cover, a supporting casing, and a battery cover. The seat has a central engaging rod and a first replacement element. The sealing module can be attached to, or detached from, the seat. The press cover includes a central engaging piece, a heat insulation block, and a second replacement element. Through engagement of the central engaging piece with the central engaging rod, the press cover can be selectively swung to press the heat insulation block against the sealing module, or to press the second replacement element against the first replacement element. The first replacement element and the second replacement element can be substituted with an appropriate module element upon demand on various functions.

  • Patent number: 7785434
    Abstract: Apparatus and methods are provided for substantially continuously forming thin-walled sleeves that may be incorporated into tubular devices sized for introduction into a patient. In one embodiment, a pair of sheets including coated surfaces oriented towards one another are directed through a cutting apparatus to cut the sheets into multiple pairs of strips. The pairs of strips are bonded together to create a plurality of sleeves having lumens defined by the coated surfaces. In another embodiment, a sheet having a coated surface is fed through a cutting tool to separate the sheet into a plurality of strips, and the strips are formed into sleeves, e.g., by feeding the strips through a die or mandrel using a substantially continuous process. Optionally, the sleeves may be subsequently cut into individual tubular devices and/or further processed, e.g., by providing one or more layers around the sleeves to create catheters, sheaths, or other apparatus.

  • Patent number: 7779880
    Abstract: A tube connecting apparatus that can carry out self reset operation without giving damage to the apparatus and that safety of an operator is considered. The tube connecting apparatus has an EEPROM memorizing information with respect to a connecting process state of tubes. When electric power is inputted, the apparatus judges whether power supply was shut off during tube connecting operation based upon the information memorized in the EEPROM with respect to the connecting process state of tubes and a detecting result of a wafer 41 according to a wafer position detecting sensor 421, and carries out reset operation. In the reset operation, the apparatus restarts and completes connecting operation (S620 to 632) by heating the wafer again to fuse the tubes adhered to the wafer (S614, 616). Error indication is displayed at a LCD display to secure connecting strength and the like (S634). A locking state is not cancelled during cooling time after heating of the wafer is stopped to secure safety (S628 to S632).
