Abstract: Simple, inexpensive and efficient tip cutting assemblies for allowing an operator to cut the tip of a fresh cartridge of caulk prior to insertion in the barrel. The tip cutting assemblies are provided in the context of two general types of caulking guns having either a metal enclosed frame or single piece molded plastic open frame. In one embodiment for a molded open-frame gun, the cartridge tip cutting assembly includes a cutting bracket attached to the frame and having an aperture there through for insertion of the cartridge tip. The cutting assembly also includes a blade assembly attached to the trigger and extending a blade outwardly between the frame and cutting bracket. Another embodiment for a closed metal-frame gun includes an aperture through a side of the housing for insertion of a cartridge tip, and a tip-cutting member formed with a through-hole to pass the plunger shaft and riding thereon within the housing.

Abstract: A dispensing apparatus for serially dispensing plastic bags from a wound roll of continuous flexible plastic bags joined along perforated severance lines. A container is provided which is adapted to receive the wound roll of plastic bags. The container has a bottom, a pair of opposed sides having an inwardly facing flange extending therefrom, and a separating tongue projecting outward from the bottom. The flanges define a self-threading slide for threading the plastic bags from the wound roll along a predetermined path onto the separating tongue. The separating tongue separates the plastic bags from the wound roll as the plastic bags engage the separation tongue along a predetermined path of travel.

Abstract: This is a cutter assembly for linerless strip media having an uncovered adhesive backing. There is a cutter mounted for transverse movement across the media and a backing bar with at least two cutting edges. The backing bar can be rotated to place one of the cutting edges in position to cooperate with the cutter to cut the media. The backing bar is rotatable about a transverse axis simultaneously with feed movement of the media at a rotational speed equal to the feed speed of the media. This causes the media to ride up on a pointed portion of a cutting edge without dragging across the cutting edge as the cutting edge moves into a use position in which the media is supported by a support surface of the cutting edge. A cleaning station cleans the previously used cutting edge as the bar is rotated. Rotating and fixed cutters can be used. The cutter is replaceable and can be supplied in combination with an associated media for which it is designed.

Each of the first and second cutting dies respectively is provided with an opposing cutting die to further restraint the suture. A blade is also provided at each cutting location for cutting the suture at a point adjacent to the respective cutting dies when the suture is restrained between the sets of dies.

A first cyclic pattern of the feed speed of the workpiece or the wire and a second cyclic pattern of the reciprocating speed of the wire are set in such a relation that the first and second cyclic patterns are synchronized at least during a time period of one of the modes of the respective cyclic patterns.

Abstract: There is disclosed herein a device for achieving and maintaining the optimum positioning of the cutting die and platen components on a die cutting machine used for cutting and scoring paper, plastic, leather, cloth, metal, and other like materials. The device compensates for inherent deviations present in each individual die cutting machine. The invention is comprised of a rigid lightweight metal substructure bonded to an overlayment of a semi-rigid material possessing a unique combination of elastic and compressible properties which allow the cutting knives in a steel rule die to lie in the same horizontal plane as the movable platen.

Abstract: An EL lamp has a perimeter that is beveled and said rear electrode is smaller in area than said front electrode due to said bevel. The lamp is made by placing an EL panel on a concave die with the rear electrode in contact with the die and shearing the edge of the lamp at an acute angle. The angle is between 30.degree. and 60.degree. and is preferably 45.degree.. The die has a radius of curvature that is 50-150 times the thickness of the panel to prevent deformation of the panel. For circular or nearly circular lamps, the entire perimeter of the lamp can be cut in a single stroke.

The process comprises a step for cutting out an optical recording medium of a predetermined size, by using a cutting edge, from the optical recording medium of a work size, which is larger than the predetermined size. The work-sized optical recording medium comprises a substrate having the recording film on its surface, a work-sized protective substrate provided on the work-sized substrate using an adhesive layer at least in an area outside of a recording area, including an outside area of the predetermined size.

Abstract: An automatic fabric pattern-matching apparatus for, a fabric (MA) which has a pattern continuous at least in the lateral direction and which is unwound and spread from a wound fabric (M) and is fed from one end thereof in the longitudinal direction of the fabric in a hanging manner via a feeding mechanism of the fabric pattern-matching apparatus. The surface of the hanging portion of the fabric (MA) fed in the hanging manner is read by a CCD camera functioning as an optical reading apparatus, so that the vertical position of the fabric (MA) is controlled for aligning the fabric pattern so as to form a lateral straight line, based on the read signal. As a result, disadvantageous phenomena such as bias or bowed patterns created by gravity are eliminated, thereby eliminating defective products due to the disadvantageous phenomena noted.

Abstract: Shaped articles are cut from a web by correspondingly shaped cutters on a drum cooperating with an anvil drum. The web is engaged by conveyor bands which pass around the cutter and anvil drums and form a continuing conveying path for the web away from the drums. The conveyor bands are clear of the article shapes cut in the web which can thus be positively separated from the web by pusher means to be drawn away from the web by their own conveying means.

Abstract: The invention is designed to improve a cutting performance and a spiral chip discharging ability. Main cutting edges 16 and auxiliary cutting edges 18 are formed along the respective sides of an upper surface 14 of a negative throw-away tip 12 and along side of bevelled corners, respectively. A rake face 22 of each main cutting edge 16 is gradually inclined toward a lower surface of the tip 12 by an angle of inclination .beta. along the extension of the main cutting edge 16 away from its adjacent auxiliary cutting edge 18 and by a rake angle .alpha. (>.beta.) along a direction perpendicular to the main cutting edge 16. The tip 12 is mounted on a cutter 9 as a rotatable cutting tool so as to discharge spiral chips during cutting. To this end, the tip 12 is mounted such that an axial rake angle, a corner angle, an angle of inclination, and a true rake angle are set in a range of -4.degree. to -10.degree., a range of 25.degree. to 60.degree., a range of 0.degree. or larger, and a range of -20.degree. to -5.

Abstract: A gas cylinder with internal time delay which is entirely self contained within the cylinder. A valve pin that controls communication between the two sides of the piston through one or more a one-way valves in the piston. As each piston is moved by a die into the cylinder body, it exposes a portion of reduced cross section on a valve pin and gas flows through a one way valve such that the effective area of the piston is reduced. When the die moves away from the workpiece, a time delay occurs and the piston is delayed until the piston moves upwardly and closes communication between the sides of the piston.

Abstract: A drive mechanism for a chain saw has a minimal vertical height. The drive mechanism is particularly useful for timber harvesting vehicles, and includes a drive motor, a holder with a clamping mechanism for clamping a chain saw guide bar, a bearing assembly allowing the holder to rotate in relation to the motor and a swivel device to convey liquid from the motor to the guide bar through closed channels and grooves. The bearing assembly and the swivel device have openings having sufficiently large inner diameters such that the bearing assembly and the swivel device fit around the motor, thereby avoiding the need for mounting those elements on top of one another.
