Patent number: 5382215Abstract: A process for producing paper bags with handles glued to the insides of the facing opening edges, includes perforating a paper web with transverse perforation lines spaced at distances corresponding to the section lengths necessary to produce the bags. At a given distance from the transverse perforation lines the handles are glued in adjacent pairs to the web in such a way that the outer handle parts project beyond the transverse perforation lines. The web is joined together into a tubular web by folding over its side edges, such that the handles face each other. The overlapping side edges that have been folded together are glued to form a seam. The sections are detached along the transverse perforation lines and each section is provided with a bottom portion at the end opposite the handles.Type: GrantFiled: November 16, 1993Date of Patent: January 17, 1995Assignee: Windmoller & HolscherInventor: Gunter Mattiebe

Patent number: 5382216Abstract: A method of manufacturing bags that are rectangular when collapsed and which comprise two superimposed flat sides, sealed at the edges, and a handle member. The method comprises the steps of: laying out a web forming three parallel subordinate webs, one extending longitudinally in the middle and one on each lateral side thereof; folding two top flanks out of the middle subordinate web to create a handle-top portion; V-folding a center strip of the middle subordinate web to create a handle member; providing the handle member with a finger slot and with depressions that allow the middle part to be pulled apart along the handle member to form a gusset; bringing the two lateral subordinate webs together; and attaching the lateral subordinate webs together along seams to create bag edges and cutting off the bags along their edges.Type: GrantFiled: December 7, 1993Date of Patent: January 17, 1995Assignee: M &W Verpackungen Mildenberger & Willing GmbHInventor: Josef Willing

Patent number: 5378220Abstract: A reusable yard waste container has a four sided rectangular shell which is open at its top end and has a flat multi-layered bottom. Two opposed sides of the shell have medial fold lines which allow the container to be collapsed to a flat orientation where it can be folded into a small package for storage. Located on the sides normal to the folding sides are upper and lower handles which facilitate handling of the container when full and erecting it from its collapsed orientation. Pockets at the bottom of the container receive weights to prevent the container from blowing away when it is left after being emptied. Snaps permit the top of the container to be closed when it is full. The container is constructed by placing four inwardly facing folds in the side walls of an elongate hollow cylindrical shell to form a rectangular cross-section shell with two pair of opposed sides.Type: GrantFiled: October 26, 1993Date of Patent: January 3, 1995Inventor: Robert W.

Patent number: 5356221Abstract: A carrying handle assembly for bags having a flat bottom and more particularly for bags having a cross or block bottom, including two strips of material bent into an L-shape cross section in their position of use, of which the one portion of each strip extending generally in a single plane is bonded with the bottom of the bag and the other portion of each strip, which are arranged alongside of each other, are provided with a carrying handle part. In order to prevent the carrying handle part from being torn out from between the portions of the strips of material, even when subjected to a heavy load, the carrying handle part includes a strip bent into the form of a letter U, having two limbs interconnected by a crosspiece, whose limbs are bonded between and to the superposed portions of the strips of material, which are themselves bonded together.Type: GrantFiled: February 17, 1993Date of Patent: October 18, 1994Assignee: Windmoeller & HoelscherInventors: Fritz Achelpohl, Hermann Sandmeier

Patent number: 5350350Abstract: An apparatus for carrying rope handles for paper bags to a paper bag forming station is disclosed. The rope handles are supplied to the bags at the entrance of the forming station before forming the bags. The apparatus includes a first and a second plurality of gripping devices (36) for gripping the handles (34) fed by a handle forming station. The first and second plurality of gripping devices (36) are arranged substantially side by side at the entrance of the bag forming station towards which they move. At least one pair of units (94, 98, 104) for taking the handles (34) is located at the entrance of the bag forming station. Also provided are members (70, 78, 88, 92) to control the inhibition of the gripping devices (36) and the actuation of the units (94, 98, 104) for taking the handles (34) from the gripping devices (36) so that the handles (34) are fed to the paper bag forming station.Type: GrantFiled: July 23, 1993Date of Patent: September 27, 1994Assignee: Curioni Sun S.r.l.Inventor: Giacomo Maccalli

Patent number: 5298007Abstract: In a method for manufacturing carrier bags of paper with paper handles glued to the outside in a continuous working cycle, firstly, in a bag machine, carrier bags without handles are manufactured. Paper handles are glued to the carrier bags in a handle application unit. The carrier bags are fed from the bag machine with the bottoms leading to the handle application unit. After the handles have been glued to the bags, the bags are removed, again with the bottoms leading.Type: GrantFiled: April 13, 1992Date of Patent: March 29, 1994Assignee: Windmoller & HolscherInventors: Fritz Achelpohl, Friedhelm Brinkmeier, Aloys Winnemoeller, Wilfried Lotz

Patent number: 5288284Abstract: The invention relates to a method for making bags preferably provided with side folds or other flat workpieces, which have a slip extending beyond their boundary. In accordance with the invention partly prefabricated bags are laterally supplied to a conveyor belt driven in a timed manner, and are seized there by grippers and fixed. By means of a glue applicator a glue strip is applied to the bag in its bottom region during the timed feeding movement of the conveyor belt. Finally, in a slip application station a slip is supplied each laterally to the conveyor belt and is placed onto the glue surface. The invention furthermore relates to an apparatus for carrying out the aforementioned method.Type: GrantFiled: December 14, 1992Date of Patent: February 22, 1994Assignee: Windmoeller & HoelscherInventors: Fritz Achelpohl, Friedhelm Mundus, Hans-Ludwig Voss

Patent number: 5222931Abstract: An apparatus and process for the attachment of a bayonet handle having a barb head defining each end thereof to a carton blank. The apparatus comprises releasable clamping means for horizontally gripping the handles. Below the clamping means are support means for flatly maintaining carton blanks. A pair of blades, situated juxtaposed opposite sides of the clamping means, are retractable between an upward retracted position and a downward extended position near the support means. The clamping means are movable between an upper handle receiving position and a lower position near the support means by descending means.The process comprises first providing a bayonet handle. The handle is next bent in two places so that the barb heads are perpendicular to an interior section of the handle and are projecting toward respective apertures in the carton blank. Then, the handle is moved such that the barb heads are inserted into the respective apertures.Type: GrantFiled: April 9, 1991Date of Patent: June 29, 1993Assignee: The Procter & Gamble CompanyInventors: John T.
