  • Patent number: 6843156
    Abstract: A trim press article handling apparatus includes a frame, a punch, a die, and a treadle. The punch is carried by the frame. The die is carried by the frame and cooperates in relative movement with the punch to sever articles from a web. The treadle is carried for movement relative to the die. The treadle includes a web guide member, a primary guide strip spaced from the guide member slightly greater than a thickness of the web, a secondary guide strip spaced from the guide member at least four thicknesses of the web and spaced apart from the primary guide strip, and an article detector carried by at least one of the primary guide strip and the secondary guide strip. The article detector is operative to detect position of an article in the web by detecting the position of a protuberance in the web as the protuberance is conveyed between the primary guide strip and the secondary guide strip.

  • Publication number: 20020178885
    Abstract: A chamfer cutting device for cutting packaging materials (9) comprises a die (1) and a knife part which has a plurality of knives (2). The die (1) can be moved toward the knife part in order to carry out a cut. The knives (2) are arranged individually in the knife part in a force-dependent manner in such a way that their position with respect to the tool plate (4) varies in a defined way as a function of the force produced by contact with the packaging material (9) or the die (1). In the event of contact between the knife (2) and the die (1), a force acts on the knife (2) which does not exceed a predefined maximum force. The chamfer cutting device has the advantage that the die (1) can be guided right up to the knives (2).

  • Patent number: 4744276
    Abstract: This invention provides a method of and apparatus for punching apertures in the walls of square sectioned steel tube. An elongated square sectioned mandrel is supported horizontally by and is connected at a rear end to roller decking so that a square tube can be fed onto the mandrel and can be used to feed the tube off the mandrel step by step, while between steps the tube is punched at the front end of the mandrel by a punch die on a punch head which moves laterally of the mandrel and into a punch recess in the mandrel. The punch head also has a guide pin which engages a guide recess in the mandrel before the punch die engages the punch recess to ensure that the punch die and punch recess are accurately aligned and that the apertures will be evenly spaced along the length of the tube.

  • Patent number: 4192449
    Abstract: A coding system for applying identifying data bits to a segment of a film strip having an integrated circuit bonded to a lead pattern formed on the segment by selectively piercing marking areas of the segment. A die of a punch press has a predetermined number, normally a power of 2, of pin holes which are arranged in a predetermined array. Piercing punches, one for each pin hole, are mounted on a punch holder for limited vertical movement with respect to the punch holder. The punches are arranged so each can be inserted into its corresponding pin hole. To prevent movement of piercing punches relative to the punch holder on which it is movably mounted and to vary the data applied to a segment, a backup pin is placed between a punch backup plate and the head of the piercing punch.

  • Patent number: 4058039
    Abstract: A method and machine adapted to removed baked waffles from a succession of waffle irons on a feed conveyor, trim the waffles so removed into a regular peripheral configuration, and transfer those waffles in succession onto a transfer conveyor. The feed conveyor is adapted to convey a series of successive waffle irons, with baked waffles thereon, from an oven to a transfer location. A vacuum head of novel structure is provided at the transfer location to move cyclically in a machine direction of the feed conveyor between an upstream and a downstream location, the vacuum head being raised and lowered during that limited motion path to pick up waffles by vacuum from successive waffle irons without stopping the conveyor. The vacuum head is also movable in the cross machine direction of the feed conveyor between the feed conveyor and a transfer conveyor.

  • Patent number: 3962941
    Abstract: A mat of filamentary material is loaded onto a transport tray formed with an array of holes having a predetermined inside diameter. The transport tray is displaced between an upper and lower platen of a press. The upper press platen is provided with an array of downwardly extending pins having an outside diameter much smaller than the inside diameter of the holes in the transport tray, each pin being alignable with a respective transport-tray hole. The lower press platen is formed with an array of upstanding tubular nipples having an outside diameter smaller than the inside diameter of the transport-tray hole and an inside diameter corresponding to the diameter of the pin. Each nipple is arrayed beneath a respective hole in the transport tray and therefore beneath a respective pin so that as the upper platen descends the pin punches a hole in the mat using the nipple as a die. The upper end of each nipples lies in the plane of the upper surface of the transport tray.

  • Patent number: RE29795
    Abstract: A self-contained unit to be attached to a power punch press to provide a feed for stock being fed to the press. The unit contains a direct drive from the punch press crankshaft to feed rolls which are located adjacent to the table of the press. A non-slip, positive, drive is provided from the crankshaft of the punch press to an index drive which receives continuous, uniform rotary motion and converts it into non-continuous, incremental movement of the index drive output shaft. A positive, non-slip drive is provided between the index drive output shaft and the power driven feed roll. The feed roll unit also contains a compressed air-operated cylinder arrangement to release the idler feed roll at a predetermined period during the punch press cycle so that the stock being fed to the press is free from the feed rolls during the pressing portion of the punch press operating cycle.
