Patent number: 5286319Abstract: An improved machine for welding pleats on fabric that employs a plurality of toothed wheels to index the fabric one pleat at a time. A pusher is positioned between each of a selected pair of adjacent wheels. The pushers are sized and configured to be capable of pushing selected pleats from the wheels to a proper position between the weld stack and anvil for welding. Additionally, the welding stacks are independently pneumatically actuated so that each welding stack may apply the proper welding pressure. A series of air blowers directs a flow of air under a just-welded pleat stripping it from the anvil.Type: GrantFiled: March 11, 1992Date of Patent: February 15, 1994Assignee: Verosol USA Inc.Inventors: Kenneth Gawne, Gordon Thompson

Patent number: 5185052Abstract: Disclosed is an apparatus for longitudinally pleating a moving lamina. The apparatus features a curved axis roll having a stationary axis circumscribed by a rotating sleeve with a plurality of circumferentially oriented grooves in the rotating sleeve. The pleats are produced by the intermeshing of the lamina with the grooves of the rotating sleeve. Preferably a complementary curved axis roll having lands which interdigitate with the grooves of the first roll is used in conjunction with the first curved axis roll.The apparatus preferably further comprises a third curved axis roll disposed upstream of the first curved axis roll to substantially equalize the paths of travel of any points on the moving lamina by compensating for differences in the paths of travel between the edges and centerline of the lamina.Type: GrantFiled: June 6, 1990Date of Patent: February 9, 1993Assignee: The Procter & Gamble CompanyInventors: Charles W. Chappell, John J. Angstadt

Patent number: 5160563Abstract: A method and apparatus for making a pleated expandable and collapsible multi-cell product for window coverings and the like. A web of material is accordion folded widthwise to form a series of web panels united in alternate succession along first and second creased folds disposed at respective first and second sides of the web. Successive panels are advanced in an unfolded condition lengthwise of the web through an adhesive applying zone to an inlet end of a refold stack and adhesive is applied to each web panel, in a band parallel to and spaced from the associated creased fold with a preceding panel. The web panels having adhesive applied thereto are refolded in succession along the associated creased fold with a preceding panel onto the inlet end of the refold stack.Type: GrantFiled: March 30, 1990Date of Patent: November 3, 1992Assignee: Graber Industries, Inc.Inventors: Darrell J. Kutchmarek, James H. Stauffacher

Patent number: 5135461Abstract: A machine (300) and the process for manufacture of a unique completely pleated product (110) which is made from a continuous, flexible web (311) for the covering of windows and the like. The machinery consists of a production line (300) with at least a screen printing assembly (306), printing phase control apparatus (330), a unique pleating assembly (400 or 800) and an optional folding assembly (500) for stacking and receiving the final product. Screen printing and web travel phasing is performed in accordance with standard practices in the industry, while the pleating and folding of the finished product is performed by apparatus designed and constructed by the instant inventors. After predetermined patterns of adhesive or bonding material (212) have been applied to the continuous web (311), it is pleated by a paired roller assembly (400 or 800) and, through the optional use of an air knife assembly (500), folded into a collecting apparatus.Type: GrantFiled: December 7, 1989Date of Patent: August 4, 1992Assignee: Comfortex CorporationInventors: John A. Corey, John T. Schnebly

Patent number: 5120376Abstract: The method and the apparatus for manufacture of a light-proof and folded window curtain are disclosed. A plane curtain material is folded repeatedly into a plurality of folded parts of an equal width, which are subsequently joined together on the same side of the curtain to form close-knit shoulders through which the curtain holes are arranged at a predetermined position for accommodating a string. A positioning apparatus is employed to hold firmly the groove portions of the folded curtain material, so as to permit two adjacent folded parts to stay closely together. An adapting apparatus is subsequently used to form a shoulder of a predetermined width from two adjoining folded parts. A series of shoulders are formed from a plurality of groups with each containing two adjoining folded parts on the same side of the folded curtain material.Type: GrantFiled: February 1, 1991Date of Patent: June 9, 1992Inventor: Amy Hong

Patent number: 5084178Abstract: The disclosure describes an arrangement which comprises a porous filter layer and a porous support layer. The porous support layer has first and second surfaces and the porous filter layer is positioned near the first surface of the porous support layer. The filter arrangement further comprises several polymeric beads disposed in parallel strips on the second surface of the porous support layer. The filter arrangement is corrugated to form pleats which extend generally perpendicular to the polymeric beads. Each pleat includes an open end, a bight end, and first and second opposing sides which extend between the open end and the bight end and include a portion within each pleat in which the opposing sides are in essentially parallel relationship. Each bead extends from the open end of the pleat along the first side to the bight end and from the bight end of the pleat along the second side to the open end.Type: GrantFiled: March 15, 1989Date of Patent: January 28, 1992Assignee: Pall CorporationInventors: John D. Miller, Joseph R. Swiezbin
