Patent number: 7175582Abstract: Methods and apparatus for controlling the registration of a first elongated continuous structure (e.g., plastic fastener tape) with attachments (e.g., sliders) or formed features (e.g., slider end stop structures), as it is fed to a sealing station, where it is joined to a second elongated continuous structure (e.g., a web of packaging material) with formed features (e.g., thermoformed troughs). The second elongated continuous structure is intermittently advanced through the machine by the same distance each advancement. During each dwell time, the first elongated continuous structure is processed, i.e., structural features are attached and/or formed. Proper registration of the structural features on the first elongated continuous structure with the second elongated continuous structure is accomplished by adjusting the distance that the unjoined upstream portion of the first elongated continuous structure advances as a function of feedback acquired downstream.Type: GrantFiled: May 9, 2005Date of Patent: February 13, 2007Assignee: Illinois Tool Works Inc.Inventor: Kevin Owen

Patent number: 7022057Abstract: A device for manufacturing packing bags from two packaging films, comprising two transport rollers, each of which pulls a film from a respective feed roll. The two films have marks printed on them at regular intervals. The transport rollers are pressed against corresponding idler rollers which between them preferably form a feed gap for the films. Downstream of the two transport rollers, there is at least one first buffer taking up slack in the assemblage of the two films or accommodating the lengths of the two films to match each other. The device can be used to synchronize two films that are printed with a regular pattern so that the patterns match.Type: GrantFiled: July 29, 2003Date of Patent: April 4, 2006Assignee: Water-Line SAInventor: Tiziano Colla

Patent number: 5993367Abstract: A method and system for determining the bonding quality of a bonded area of a flapped boxmaking blank in a boxmaking apparatus at an assembling station of a production line, where opposite end portions of the blank are bonded together with confronting edges of companion end flaps defining a required gap, in terms of the outline of the gap. The quality determination is accomplished by irradiating sheetlike light onto the bonded area across the gap, forming an image of the irradiated light as a light image line composed of discrete segments which are arranged along a reference line for the flap portions and include at least one line segment located off the reference line, computing a ratio of a length of the off-line segment to the entire length of the light image line to obtain a width of the gap, and comparing the width of the gap with a preset reference value.Type: GrantFiled: July 9, 1998Date of Patent: November 30, 1999Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Koji Hattori, Yasuyuki Baba, Yasunari Suzuki

Patent number: 5782731Abstract: For manufacturing cross bottom valve sacks, the ends of continuously transported tubular sections are opened out with the formation of so-called "bottom squares" with triangular corner folds lying opposite each other. A valve leaf or a valve tube is tacked onto one side of an opened-out bottom square in such a way that, after the side folds of the opened-out bottom have been folded-in with a mutual overlap, the leaf forms a valve tube leading into the inside of the sack, and with its outer end freely accessible at one side of the sack bottom. For checking the correct position of the valve leaves or of the valve tube, the valve leaf or the valve tube, or the zone of the corner fold, covered thereby when the leaf is tacked in its correct position, is provided with a mark that can be registered by a photocell device fixed to the frame. The photocell device is activated by a reference pulse when, in the manufacturing installation, the sack bottom has reached its predetermined position to be checked.Type: GrantFiled: January 29, 1996Date of Patent: July 21, 1998Assignee: Windmoeller & HoelscherInventors: Uwe Kohn, Rainer Henze

Patent number: 4283185Abstract: Box blanks produced from a moving web by a paperboard corrugator are shingled on a stacker conveyor. The corrugator includes a shear which severs the web in response to a production run change signal into leading and trailing portions. A cut-off machine cuts the severed web portions into the box blanks. Box blanks cut from the leading portion of the severed web are part of the old production run. Box blanks cut from the trailing portion of the severed web are part of the new production run. The leading edge of the trailing portion of the severed web is tracked to the cut-off machine. The trailing edge of the first full size box blank of the new production run is detected at a first position relative to the stacker conveyor. The trailing edge of the first full size box blank is then tracked to a second position on the stacker conveyor. When the trailing edge of the first full size box blank reaches the second position, a command signal is generated.Type: GrantFiled: October 9, 1979Date of Patent: August 11, 1981Assignee: Molins Machine Company, Inc.Inventors: A.
