Patent number: 8177697Abstract: A dunnage conversion machine (36) converts a sheet stock material into a dunnage product that is relatively thicker and less dense than the stock material, but is relatively thin and sufficiently flexible to function as a protective wrap. The conversion machine includes a feed mechanism (40) that advances a sheet stock material therethrough and a connecting mechanism (42) downstream of the feed mechanism. The connecting mechanism retards the passage of the sheet stock material therethrough by feeding the stock material therethrough at a slower rate than the feed mechanism feeds the stock material to the connecting mechanism. This causes the stock material to randomly crumple in a longitudinal space between the feed mechanism and the connecting mechanism. The connecting mechanism connects multiple overlapping layers of sheet stock material together as they pass therethrough, including connecting at least one crumpled sheet to one side of one other sheet.Type: GrantFiled: April 26, 2011Date of Patent: May 15, 2012Assignee: Ranpak Corp.Inventors: Robert C.

Patent number: 6699167Abstract: A cushioning conversion machine having a novel former around which a sheet material is folded to form an improved cushioning product. The former has longitudinally spaced side surfaces inclined from bottom to top toward a downstream end of the machine. The side surfaces cause the obstruction of the sheet stock material upstream of the side surfaces so that the sheet material crumples in the spaces upstream of the side surfaces, thereby increasing the cushioning properties of pillow portions of the cushioning product. The former also has a centrally located base plate which minimizes crumpling in a central portion of the sheet material so that the folded over portions and the central portion can be connected to maintain more effectively the shape of the pillow portions in the resulting cushioning product. In addition, the former has a guard plate mounted above longitudinally spaced bottom edges extending laterally outwardly from the base plate and upstream from a vertical central plane.Type: GrantFiled: February 19, 2002Date of Patent: March 2, 2004Assignee: Ranpak Corp.Inventor: Thomas E.

Patent number: 6428459Abstract: A protective furniture shipment and storage bag is formed as an envelope comprised of inner and outer transparent film layers with protective cushioning foam elements sandwiched therebetween at opposite ends of the envelope to define a furniture viewing window longitudinally between the foam elements. Such bags are fabricated by sandwiching foam elements in spaced relation between two essentially coextensive transparent film layers, folding the sandwiched components along the longitudinal fold line, and heat sealing or otherwise attaching the folded film layers and foam elements at the opposite ends to form the aforedescribed envelope.Type: GrantFiled: January 25, 2001Date of Patent: August 6, 2002Inventor: Robert L.

Patent number: 6183586Abstract: A process is for the production of a padding material (7) made from paper or similar flat structures that are folded together and are formed by tools. At least one intermediate layer (3, 4) is perhaps incorporated within a top layer (2) that is to be folded together. The top layer and the intermediate layer that may or may not be provided are formed along their narrow sides by at least one forming tool (10, 11) after the top layer has been folded together. An intermittent transport unit acts on the structure (1) that is still flat but has been folded together. This causes the structure to be formed longitudinally, in addition to the forming that is carried out by the forming tool (10, 11).Type: GrantFiled: June 10, 1997Date of Patent: February 6, 2001Inventor: Peter Heidelberger

Patent number: 6168559Abstract: A cushioning conversion machine (10) comprising conversion assemblies (52, 54) which convert a sheet-like material (22) into a continuous strip (30) of a cushioning product; a cutting assembly (56) which cuts a leading portion of the strip (30) into a cut pad (32) of a desired length; and a pad-transferring assembly (12). The pad-transferring assembly (12) is mounted to the machine's frame (36) downstream of the cutting assembly (56) and it is designed to engage the leading portion of the strip (30) prior to it being cut. Once the strip (30) is cut, and the pad (32) is formed, the pad-transferring assembly (12) transfers the cut pad (32) away from the cutting assembly (56).Type: GrantFiled: November 19, 1993Date of Patent: January 2, 2001Assignee: Ranpak Corp.Inventor: James A.

Patent number: 5573491Abstract: A method and apparatus characterized by slitting a sheet of material having a natural resilience into a plurality of strips to form a body of such strips and folding each of the strips into a zig-zag shape. The folding step/function is accomplished by advancing the plurality of strips against a restriction acting on the body of strips in such a manner that the natural resilience of the material produces substantially uniform adjacent opposite folds thereby causing each of the strips to assume a zig-zag shape.Type: GrantFiled: December 21, 1994Date of Patent: November 12, 1996Assignee: Ranpak Corp.Inventor: Johnny M.

Patent number: 5525176Abstract: Crimped paper articles are reinforced by rolling a piece of paper around a sleeve and pressing one end of the paper and sleeve against a hard surface. The sleeve is repeatedly lifted in small increments and the paper is pushed down towards the hard surface, creating crimps in the paper. When the paper is substantially crimped, it is removed from the sleeve and straightened. Vinyl duct tape or another resilient material is applied to the underside of the paper for reinforcement, and the paper is formed into a useful or art article. The vinyl tape makes the article stronger and more configurable. The vinyl tape also keeps the article from losing its shape. Transparent tape can be applied to the outer surface of the articles to further protect the articles from dehydration, humidity and decay.Type: GrantFiled: May 22, 1995Date of Patent: June 11, 1996Inventor: James Z.

Patent number: 5211620Abstract: A cushioning conversion machine for converting a sheet-like stock material, which may be viewed as having two edge sections and a central section, into a cushioning product is provided. The machine includes a conversion assembly for converting the sheet-like stock material into a cushioning product and a supply assembly which supplies the sheet-like stock material to the conversion assembly. The stock material is supplied to the conversion assembly in such a manner that its edge sections must travel in a longer path than the central section thereby creating edge-tension in the edge sections of the stock material. While a certain minimum conversion-tension is necessary in the edge sections of the stock material to properly convert the stock material into a cushioning product, a certain continuous tearing-tension, greater than the minimum conversion-tension, will cause a continuous tear in the stock material.Type: GrantFiled: November 1, 1991Date of Patent: May 18, 1993Assignee: Ranpak Corp.Inventors: Richard O. Ratzel, James A. Simmons
