Patent number: 5643396Abstract: This invention pertains to apparatus for use in constructing a garment including a stretched elastic. Specifically, the invention contemplates incorporating stretched elastic into a continuous web, including one or more segments which exert retractive forces in directions counterproductive to the function of either the web, the garment, or both, and nullifying that portion of the stretched elastic which would be counterproductive. The elastics may be cut at appropriate loci. The stretch may be intermittently reduced or eliminated on one or more selected ones of the elastics as the elastics are incorporated into the web. A special coating may be used on the processing rolls to maintain the width dimension of the web at loci disposed after incorporation of elastic stretched across the transverse dimension of the web. Transverse bonds may be formed on the web using a rotary carrying drum, and energy application devices which rotate with the drum, to increase bond forming time.Type: GrantFiled: May 30, 1995Date of Patent: July 1, 1997Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Gregory John Rajala, Paul Daniel Suke, Steven Craig Gehling, Gerald Leigh Rabe

Patent number: 4924884Abstract: A continuous filter tow is advanced through a combined wrapping and condensing station by an endless belt, and the thickness of the belt decreases as a result of wear. The resistance which the condensed tow offers to the flow of air is measured by a pneumatic detector at the aforementioned station, and the accuracy of such measurement is affected by decreasing thickness of the belt as a result of increasing rate of escape of testing fluid along the belt. Therefore, the thickness of the belt is monitored and signals which are generated to denote the thickness of the belt are used to correct signals which are generated to denote the resistance to the flow of air. The correction involves modifying the signals denoting the resistance to the flow of air to denote a more pronounced resistance proportionally with decreasing thickness of the belt.Type: GrantFiled: February 6, 1989Date of Patent: May 15, 1990Assignee: Korber AGInventors: Nikolaus Hausler, Heidi Muller, Peter Pinck, Christina Straube

The retaining member is movable and is shaped so that during movement into different positions of orientation, it will maintain its function of holding the core wrap closed.Type: GrantFiled: March 18, 1985Date of Patent: March 3, 1987Assignee: Northern Telecom LimitedInventors: Robert J. Howat, Kenneth R. Kirkwood

Patent number: 4622092Abstract: A bonded ASP cable includes a multiconductor core which is filled with a waterproofing material. The core is enclosed by a plastic layer (28) which is flooded with a waterproofing material. Wrapped longitudinally about the plastic layer is a corrugated inner shield (31) having a longitudinal seam (35) and having an outer surface covered with a waterproofing material. The inner shield is enclosed by a corrugated outer shield (36) which has an overlapped longitudinal seam (38) and which has an outer surface coated with a layer of an adhesive material. As the outer shield is being formed, a sealant material is introduced into engagement with the inner shield in the vicinity of the longitudinal edge portions of the outer shield. Then as the longitudinal edge portions of the outer shield are overlapped and engaged with each other, the sealant material is caused to flow into cavities between the two shields adjacent to the seam of the outer shield to form a gasket (66).Type: GrantFiled: May 31, 1985Date of Patent: November 11, 1986Assignee: AT&T TechnologiesInventors: William D. Bohannon, Jr., Herbert E. Brent, Alfred S. Hamilton, Michael D. Kinard

Patent number: 4620895Abstract: A square filler for water treatment and an apparatus for the manufacture thereof are disclosed. The square filler is used as a contact medium for aerobic or anaerobic treatment of sewage.The square filler is made of synthetic resin net sheet or net tube of which a plurality of net layers are formed, and melt-bonding is applied to at least one spot on each layer for fixing all layers together.An apparatus for manufacturing square fillers flattens the net sheet or net tube for forming net layers with the application of pressure, intermittently feeds the flattened net sheet or net tube in the longitudinal axial direction thereof, and heats the net sheet or net tube for softening during transfer thereof.The heated net sheet or net tube is locally pressed with projections for melt-bonding so that net layers are locally melt-bonded to each other, thereby square fillers having net layers fixed by solidification thereof are obtained.Type: GrantFiled: July 31, 1985Date of Patent: November 4, 1986Inventor: Masashi Kato

Patent number: 4606784Abstract: In the manufacture of packing containers from laminated material contact between the inner layer of the material and the contents is avoided by doubling up the cut edges present in the packing container. It has proved to be difficult to perform a secure folding and sealing of the folded edge without damage to the material, since the outer, water-tight layer of the material consists of very thin, heat-sensitive thermoplastic. This difficulty is overcome by carrying out the folding and sealing of the edge of the material web gradually while at the same time supplying heat or glue. By supplying the sealing-promoting agent as late as possible during the course of folding, damage to the material as well as to the folding arrangement is avoided.Type: GrantFiled: November 3, 1982Date of Patent: August 19, 1986Assignee: Tetra Pak International ABInventors: Jan-Erik Glans, Henry Corneliusson

Patent number: 4557787Abstract: In a thermo-cementing and folding machine, a gear pump operates to supply adhesive at a rate which is dependent upon the speed of rotation of a main drive shaft, by which workpiece feeding means of the machine is driven. The machine has also a facility for varying the rate of feed of a workpiece by the workpiece feeding means without varying the speed of rotation of the main drive shaft. The ratio of the rotational speed of the shaft to the operating rate of the pump is varied in response to variation of the workpiece feed rate. This arrangement is achieved by computer control, the gear pump being driven by a stepping motor for this purpose. In addition, at the end of each work cycle, use of a stepping motor facilitates "suck back" of adhesive, and a "fast forward" adhesive upon initiation of the next work cycle.Type: GrantFiled: November 23, 1983Date of Patent: December 10, 1985Assignee: USM CorporationInventors: Graham J. Mansfield, Dennis S. Hall, Ewen R. Cameron
