| 20080282863 | MECHANISM AND METHOD FOR PREDETERMINED ANGULAR CUTTING OF A PLURALITY OF PLY STRIPS - Apparatus for cutting plural aligned ply strips includes plural knife blades disposed in a spaced manner such that each knife blade is aligned with and in closely spaced relation to an associated ply strip. The knife blades are pivotally mounted in a common housing and are coupled to a single rotational drive for allowing each knife blade to assume the same predetermined cutting angle relative to its associated ply strip, where the cutting angle may be varied between ±45°. The plural knife blades are coupled to a rotational drive by means of plural circular drive gears and are connected to a linear drive for displacing the knife blades into contact with the ply strips for cutting the strips at the predetermined angle. The severed edges of the aligned ply strips are formed in mutual linear alignment and do not include projecting triangular patterns, or crenelations. | 11-20-2008 |

| 20090007747 | LIVE TOOLING SYSTEMS FOR MACHINE TOOLS - In conventional ram-driven presses, the downward stroke of the ram into a tool causes acceleration of the tool, thereby facilitating an operation on a workpiece by the tip of the tool. While the ram stroke is found to impart sufficient dynamic energy to the tool to facilitate the necessitated operation by the tool tip, there are other more efficient, and in turn, more effective, means and methods of actuating the tool tip, with such means and methods being facilitated from energy derived from the tool's acceleration or from energy from other external sources. | 01-08-2009 |
| 20090188364 | Punch Press - The invention relates to a punch press, in which compressive machining is performed on a blank. The punch press includes tools, a ram, a drive element of the ram, and a precise-positioning operating device for moving the drive element of the ram, as well as a precise-positioning moving element for moving the ram in the direction of the tool row to the location of the desired tool. According to the invention the moving element of the ram is arranged to operate using the same moving operating device of the ram. | 07-30-2009 |
| 20100095824 | Reprocessed Dies - A method includes removing material from a die and thereby changing a location of a cutting edge of the die in a punch entry direction and changing a cutting edge cross-section of the die; and assigning a punch and/or a workpiece thickness to the die based, at least in part, on the change in the cutting edge cross-section of the die. | 04-22-2010 |
| 20110005363 | Multi-purpose hole punch - A multi-purpose hole punch, having a main body pivotal configured with a pivot shaft, an upper end of which is pivotal configured with a press plate, and the lower end is connected to a base plate, thereby forming a gap between the main body and the base plate. Each through hole of three sides of the main body has a key-press, and a punch is located in each of the through holes beneath the key-press. Two joined transform plates are pivotal configured on two sides in the gap. One of the transform plates is configured with an unfilled corner able to fixedly position a corner of paper, while the other transform plate forms an unfilled corner able to fixedly position the edge of paper. Accordingly, rotating the press plate and pressing the key-presses above the two unfilled corners enables punching holes in the corner and margin of the paper. | 01-13-2011 |
| 20130047810 | MECHANISM AND METHOD FOR PREDETERMINED ANGULAR CUTTING OF A PLURALITY OF PLY STRIPS - Apparatus for cutting plural aligned ply strips includes plural knife blades disposed in a spaced manner such that each knife blade is aligned with and in closely spaced relation to an associated ply strip. The knife blades are pivotally mounted in a common housing and are coupled to a single rotational drive for allowing each knife blade to assume the same predetermined cutting angle relative to its associated ply strip, where the cutting angle may be varied between ±45°. The plural knife blades are coupled to a rotational drive by means of plural circular drive gears and are connected to a linear drive for displacing the knife blades into contact with the ply strips for cutting the strips at the predetermined angle. The severed edges of the aligned ply strips are formed in mutual linear alignment and do not include projecting triangular patterns, or crenelations. | 02-28-2013 |
| 20140020541 | SWITCHABLE HOLE PUNCH APPARATUS - An apparatus for punching holes is provided. The apparatus may include a base movable from a first position to a second position and first and second punch assemblies attached to and movable with the base. The punch assemblies may each include parallel punches movable relative to the base and having an end. The apparatus may include first and second cams fixed to a rotatable shaft and having an engagement portion for engagement with the ends of the respective punches at a predetermined rotation position of the shaft. When the base is in the first position, rotation of the shaft to the predetermined rotation position may cause movement of only one of the punches relative to the base. When the base is in the second position, rotation of the shaft to the predetermined rotation position may cause movement of only the other punch of the punch assemblies. | 01-23-2014 |
| 20150343657 | FOOD COMMINUTION DEVICE - The invention relates to a food comminution device having a base part, which has a receptacle for a cutting insert with at least one cutting blade, and having an actuation part, which is articulatedly connected to the base part and which, for pushing through food items for comminution, can be pivoted towards the cutting insert. The food comminution device is characterized in that a cutting insert with mutually spatially separate cutting regions, said cutting regions being separated from one another by an intermediate web, or a cutting insert with an uninterrupted cutting blade arrangement, in particular a cutting blade arrangement which is not interrupted by an intermediate web, or multiple separate cutting inserts simultaneously, in particular cutting inserts each with a separate frame, can be selectively fitted into the receptacle and used. | 12-03-2015 |

| 20100212469 | Multiple Punch and Die Assembly Providing Hand Disassembly, Punch Length Adjustment and Replacement - A multiple punch and multiple die assembly has a workpiece protector comprising a punch lifter that is operatively associated with each punch for supporting each of the punches in an inactive position as an active punch is moved by the ram to the active, i.e. operating position to thereby eliminate scoring or marking of the sheet material or other workpiece that is being punched. To eliminate the need for hand tools and hand assembly or disassembly, a manually moveable retainer on the punch assembly is provided that can be moved by hand between a punch-releasing and punch-retaining position for holding the punches within the multi-punch assembly during operation. To prevent stress fractures that formerly occurred in die carriers, support of each die is distributed between two different die components thereby reducing impact stress on the carrier as the ram drives the punch through the workpiece. | 08-26-2010 |
| 20120279369 | PUNCH PRESS - A punch press includes plural dies and plural punches, and punches a work by a punch and a die that are set at a work position. The punch press includes a lifter for lifting the die to be set at the work position up to a path line of the work, a die-support member movably provided on a die-side of the lifter, and a die supporter provided on the die-support member for supporting the die set at the work position in a state where the die has been selectively lifted up to the path line by the lifter. According to the punch press, contacts between a work and dies while conveying the work can be prevented. | 11-08-2012 |
| 20160089710 | PUNCH PRESS - A punch press includes a punch support body, on which a plurality of punches are mounted, and an integrated die support body positioned below the integrated punch support body and including a plurality of dies mounted thereon to perform a punching process in cooperation with the punches. The plurality of the dies are juxtaposed along a rim of the integrated die support body. The integrated die support body includes an integrated die support main body and an in-and-out moving body that enables at least a portion thereof to assume a condition emerging out of the rim of the integrated die support body while its connection with the integrated die support main body is retained. Some of the dies disposed in the integrated die support body are disposed in the in-and-out moving body. | 03-31-2016 |
