Abstract: A cutting guide having a seam allowance recess and methods of cutting a piece of material with such cutting guide.

Abstract: A spark trap device for containing sparks and metal filings generated when a chop saw cuts a metal includes a base plate receiving a chop saw to collect sparks and metal filings from the chop saw. Each of a pair of channels is coupled to opposing sides of the base plate and the chops saw is positioned between the channels. Each of the channels has one of a pair side walls coupled thereto and extending upwardly therefrom. A rear wall is coupled to and extends upwardly from a rear end of the base plate and is coupled to the side walls. A lid is hingedly coupled to the rear wall. The lid extends between the side walls when the lid is positioned over the side walls. The rear wall, the side walls and the lid deflect the sparks towards the base plate when the chop saw is in use.

Abstract: The cutting tool for polyurethane elastomers, which is controllable manually or program-controlled comprising a cutting head (10) with a driving device (20), a blade holder (30) with a cutting knife (35) has at least one cutting head. The driving device has a driving motor (21) with a drive shaft (22) running in cutting head longitudinal axis (L), a cam disk actively connected with the drive shaft (22) of the driving motor (21), driven rotating about the drive shaft longitudinal axis (L2), with control surfaces (40, 41) configured on the side (25a) opposed to the driving motor (21) and lying in different planes, a roller (26) actively connected with one of the control surfaces (40. 41) of the cam disk (25), a lifting rod or tappet push rod (45) actuated by means of a spring (27) which is actively connected with the roller (26) and the cam disk (25) over a coupling piece (46) and which carries at its free end (45a) the blade holder (30) for the cutting knife (25).

Abstract: An improved automatic board cutoff saw that maintains better positional accuracy at higher board speeds is disclosed. The improved automatic cutoff saw includes an overhead belt conveyor including a first belt for starting, stopping and advancing the board in frictional engagement therewith over a substantial length both upstream and downstream from a crosscut saw station, as well as a second belt conveyor disposed beneath the first belt conveyor near an infeed region of the crosscut saw station for engaging the underside of the board during its advancement through therethrough. One of a pair of rollers disposed on a pivotal arm of the overhead belt conveyor, the arm being pivoted by tension in the first belt, is urged into a position whereby a board, which may be of scant height, nevertheless is positively, frictionally engaged by both belt conveyors at least during the critical infeed phase of the board-advancing operation.

Abstract: The object of the invention is to reduce the number of the producing processes of an IC lead frame.In the present invention, a plurality of punches 17 are provided protruding from the base 16 in such a manner that their surfaces are disposed approximately radially, and the reinforcing punch 23 which connects the cutting blades 18 of the punches 17 with each other, is provided between the cutting blades 18, and protruding from the base 16.The punches 17 are integrated by the reinforcing punch 23, so that the strength of each punch 17 is improved and the number of punched holes in one process can be increased.

Abstract: A hedge cutting bar is shown and described as having rivets for securing a cutting blade between a retaining blade and a stationary blade. The rivet structure includes a central flange and distal hubs whereby the central flange may occupy slots in the cutting blade while the hubs attach within respective mounting apertures of the stationary blade and the retaining blade. The thickness of the flange is greater than the thickness of the cutting blade whereby a gripping force provided by the rivet is taken up at the flange to avoid pinching of the cutting blade between the stationary blade and the retaining blade. The described fastening arrangement is less suspectable to loosening under the vibrational forces imposed during use of the hedge cutting bar than that of prior fastening arrangements.

Abstract: An auxiliary punching device is disclosed, which is attachable to a machine for punching holes at one given location into a stack of sheets of given size, in order to punch other holes at another given location in the same stack at the very same time as the holes are punched at the one location. This auxiliary punching device comprises an auxiliary die and an auxiliary punching tool that are attachable to the main die and punching tool of the punching machine to work in unison therewith. Both of the structural elements are very easy to adjust to fit any required positioning or configuration for the second row of holes to be punched, whatever be the size of the stack of sheets fed to the machine.

Abstract: A tire cutting tool wherein a curved hardened cutter blade is hydraulically driven to cuttably engage a tire between the cutting face of the cutter blades and open faces of a cutter anvil with a beginning end of the cutter blade entering between the open faces and holding the cutter blade in one plane as the blade is forced through the tire.

Abstract: The invention relates to a device for cutting stacked product (25) in sheet form having a table (12), the surface of which has an operating area, above which there is a cutting blade (2) and a pressing beam (3), behind it a feed area to receive the product to be cut and in front of it an output area to receive the cut product, and having a forward feed apparatus for the product to be cut.In order to avoid strenuous mechanical and ergonomically harmful work when turning the product to be cut, in particular in conjunction with the edge trimming of the product, it is proposed according to the invention to provide in the region of the feed area a gripper system (29) for turning the product to be cut in the plane of the table surface.

Abstract: A platen press designed for cutting, creasing or embossing sheet-like materials includes a lower movable beam carrying the sheet, and an upper beam stationary beam or which a tool is fitted. To avoid bending of the tool which has a shape of a plate in an operating position at least one of a chamber of an inner volume of the upper beam is isolated from the atmosphere and is connected to a vacuum source and has a duct extending from the one chamber to a lower surface of the beam adjacent the back surface of the plate forming the tool so as to apply a suction between the tool and the lower surface to hold the tool against the lower surface.

Abstract: Hydraulic sawing cycle control system for an undercut swing saw. Hydromotor 5 with crankshaft 7 fitted thereon without play drives the sawing lever arm 2 via a connecting rod 3. One revolution of the hydromotor corresponds to one saw cut. The hydromotor 5 is thereby controlled via a proportional valve. The path of movement of the sawing cycle can advantageously be regulated.
