  • Patent number: 9193085
    Abstract: At the time of transfer of a strip-shaped rubber member (15) onto a belt conveyor (12) by a transfer unit, support members (61), each of which is provided on one width-direction side of a corresponding belt (51) and is projectable from a conveying surface of the belt (51), are lifted by a lifting/lowering unit (71) to project from the conveying surface of the belts (51), so that the strip-shaped rubber member (15) is raised from the conveying surface of the belts (51). Therefore, the strip-shaped rubber member (15) is not in sliding contact with the conveying surface of the belts (51) at the time of transfer. As a result, a situation whereby the belts (51) are dragged by the strip-shaped rubber member (15) so that one width-direction edge portion thereof is turned up can be prevented.

  • Publication number: 20110258858
    Abstract: The present invention provides a method and apparatus of reducing current requirements by increasing resistance of the blade structure by reducing the cross sectional area of at least one section of the blade so that the electrical current requirements for heating of the blade to cutting temperature are reduced wherein the power supply and substantially entire unit may be mounted within a hand held unit. Methods of shaping blades to perform various heat distributions for specialty blades for custom cutting are disclosed. Further, an improved blade mounting structure is provided which includes structure for maintaining the legs of the blade parallel to the direction of cut and provides for easy insertion of new blades by maintaining a slotted blade cradle stable and in alignment with the blades and a clamp member away from the blade when the clamp mounting structure is loosened.

  • 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.

  • Patent number: 7950314
    Abstract: At the time of cutting stacked sheet members, a knife or a punch pierces the sheet members at positions such as along a cutting line, in a region outside the cutting line, or in a seam allowance inside the cutting line. By moving the knife or the punch vertically, heat is applied to the sheet members such that the seam members are welded (i.e., fused) together vertically. Even if at the time of cutting stacked sheet members having low air permeability, it is possible to prevent warpage or slippage of the sheet members, and cutting is performed accurately.

  • Patent number: 7819111
    Abstract: A bimodal tile saw includes a tray supported on a base extending in a first direction and a water-cooled saw unit suspended from a telescoping arm. Both the tray and the saw unit move relative to the base along the first direction. In a first mode, the saw unit is fixed and the substrate is fed to the saw unit by advancing the tray. In a second mode, the table is fixed and the telescoping arm is advanced using ergonomic handles to bring the blade into contact with the substrate. A laser cutting guide casts a precise beam across the work piece for accurate cutting. An integrated handtruck, having a handle and folding legs actuated by gas pistons allows easy transport and setup of the tile saw. During use, a retractable foot elevates the wheels off of the ground. Water shields protect the saw unit's motor and external environment.
