A non-linear adhesion knife penetrates the bag pack and adheres adjacent bag blanks together in the bag pack. An aperture maker forms means for suspending the pack from a dispensing rack. The pack is attached to the dispensing rack and the front wall of the subsequent bag will be adhered to the rear wall of a first bag, thereby causing the first bag to open when pulled from the rack.

Abstract: A method for cutting a ribbon of rubber-coated fabric includes dragging a free end of the ribbon past a working position of a punching device, forming a notch between two adjacent reinforcing cords of the ribbon using the punching device, moving a counter-blade of the punching device away from the working position, inserting at least one cutting blade through the notch, and performing first and second cuts of the ribbon. An associated apparatus includes a punching device and a cutting device. The punching device includes an incision tool, an abutting counter-blade, and control devices for moving the incision tool and the abutting counter-blade toward and away from the ribbon. The cutting device includes at least one cutting blade and a control device for moving the at least one cutting blade toward and away from the ribbon.

Abstract: A printer with a cutter does not have cutting problems caused by adhesive squeezed from label paper. In a scissor type automatic cutter 20 the contact force between the cutting edge 22a of the movable knife 22 and the cutting edge 21a of the fixed knife 21 weakens at the other side of the paper width, and as the movable knife 22 pivots, adhesive between the web liner 11a and the continuous label 11b medium is squeezed out from the label paper 11 at the distal end side of the movable knife 22 and sticks to the fixed knife 21 or the movable knife 22. Because a notched opening 44 is formed in the upstream edge 50a in the paper discharge direction at the other edge part in the paper width direction of the substantially horizontal stage surface 40 that defines the bottom edge 5a of the paper exit 5, if adhesive sticking to the fixed knife 21 or movable knife 22 moves to the stage surface 40 side, the adhesive can be removed from the notched opening 44 and does not accumulate on the stage surface 40.

Abstract: This invention generally relates to enlarging a hole in a substrate such that the enlarged hole is centered on the existing hole. A knock-out punch and die tool for enlarging a knock-out hole in an electrical box includes a punch; a generally cup shaped die; a threaded central shaft supporting the punch on one end and the die on the other end; a removable centering element placed in a cup portion of the die; and a resilient element, such as a spring, urging the centering element in an axial direction along a length of the shaft outwardly of the cup portion. The centering element and the spring may be provided as a retrofitting kit for converting non-centering punch and die tools into centering punch and die tools.

Abstract: A grid pattern punch type multiaxis punch device is capable of simultaneously punching punched holes of the same shape showing different shapes for every location at each of the same positions in each of the areas defined in a work. Every time a work is moved in X-axis, Y-axis directions under its controlled state, a hammer holder is moved in a horizontal direction under its controlled state, a punch drive source (a servo motor) is driven under a state in which hammers are corresponded just above optional punches at the same positions in each group of units, each of the punches present at the same positions in the group of units is punched by each of the hammers, thereby the punch holes having the same shapes showing different shapes for every location are punched simultaneously at each of the same locations within each area defined in the work.

According to various aspects of the invention, a tool having a cutting edge and a notching element is provided as well as a method of making the tool, and a method of changing a depth of notching by changing an angle of rotation relative to a cutting plane is described.

Abstract: The invention provides an improved method and apparatus to prepare trim cap material for bending, the apparatus comprising at least one notcher and at least one dimpler employed: (1) to notch the trim cap material to facilitate bending, but ensuring that the notch is not so large or deep so as to result in cracking when the trim cap material is bent resulting in unsightly appearance and performance deficiencies when the trim cap is installed as part of a completed sign and (2) to dimple the trim cap material so that the dimple is visible from both sides of the trim cap material.

Abstract: A tax stamp perforator and notcher applies a diagonal line of spaced apart perforations on a tax stamp for subsequent application to a cigarette pack. The stamp is glued or otherwise applied to the cigarette pack normally across the back of the pack and one of the sides thereof. When the cigarette pack is opened the tax stamp is torn along the line of perforations. In order to facilitate rapid application of tax stamps to a production line of cigarette packs, notches in the form of lines of increased densification are applied to each stamp in the area where the stamp is bent around the side of the cigarette pack. These lines of increased densification are arranged parallel to the edge of the cigarette pack, and preferably one of the lines lies along the edge of the cigarette pack to thereby reduce the ability of the tax stamp to spring back away from the pack when glued to the pack. This feature enables the stamps to be applied to the packs at high production rates.

Abstract: A cutoff system for exterior siding which includes a flying punch and shear. The system includes a main carriage which is adapted to reciprocate and, in one direction of travel, move at the same speed as the siding to be cut. A pair of punches are then actuated to form the hanger and butt notches at the lateral edges of the siding. Upon withdrawal of the punches, the travel of the main cylinder is slowed such that the siding travels away from the punching area. Upon sensing the notched areas, the main carriage is again moved to travel at the same speed as the siding. The speed is timed such that the center of the notches is located below a shear. This shear is then actuated to form a single parting line across the siding. The carriage is then retracted to await the next cycle of the system. As such, with each cycle of the system, the notches are formed in the trailing and leading edges of adjacent panel segments, and the leading panel segment cut from the continuous siding.

Abstract: A support means is provided with a pair of fixed dies aligned in spaced, horizontal relationship for receiving a metal strip having a base portion with edge portions extending in planes different from that of the base portion to be cut. Cutting die means are movably carried by the support means with actuating means connected to the movable die means for cutting the base portion and the edge portion of the metal strip supported on the spaced fixed dies with the cutting dies being shaped so that the angle cut on the base portion by the cutting die means is different from the angle cut by the cutting die means on the edge portions of the metal strip.
