Patent number: 4966639Abstract: A reinforced film of a laminate construction is thermally adhered to an edge of a web of paper stock in preparation for forming a reinforced edge of a file folder. The film has two layers, each having different characteristics, where the bottom layer becomes thermally active as an adhesive at a temperature substantially lower than the activation temperature of the other layer. The film is applied by directly heating the top layer to a temperature which in turn heats the bottom layer to a temperature where it acts as an adhesive. The layers can include a printed surface intermediate the film which is visible through the top layer or the layers can include an appropriate pigment to color code the edge of the folder. The apparatus can be added to existing file folder machines to apply the film without the need for sophisticated controls to tie the apparatus to the operation of the file folder machine.Type: GrantFiled: February 18, 1987Date of Patent: October 30, 1990Assignee: Wright Line of Canada Ltd.Inventors: George Pfeffer, Donald T.

Patent number: 4580815Abstract: A composite strip for preparation of a substrate edge for application of labels is disclosed. The composite strip comprises an elongated carrier web having an upper surface and a lower surface with the lower surface having a pressure sensitive adhesive backing covered with a removable release sheet. A high tensile strength film, such as that sold under the trademark "Mylar" by DuPont made of a polyethylene terephthalate, according to the preferred embodiment is directly bonded to the upper surface of the carrier web by a further adhesive. This film provides a receptor surface for receiving labels. The film is of a width equal to or less than the width of the carrier web and of a width to receive a label therein. This composite strip has proven useful in preparing a substrate, such as on existing file folder tab or the edge of an x-ray jacket for the subsequent application of a discrete series of labels applied about the edge of the substrate.Type: GrantFiled: August 8, 1983Date of Patent: April 8, 1986Assignee: Datafile LimitedInventor: Donald T.

Patent number: 4523776Abstract: A method for adding a reinforced labelled tab to a folder edge of a file folder of a file system is disclosed. The tab is prepared by applying a plurality of labels to a carrier web which has a pressure sensitive adhesive backing covered by a removable protective strip. A transparent reinforcing high tensile strength film is bonded to the carrier web and over the labels. A tab extension member is added to an edge of a file folder by use of the carrier web. The extension member is approximately the same thickness as the folder edge and the carrier web is of a width more than twice the width of the extension member so as to be securable to the spaced sides along the folder edge. The protective strip is removed and the carrier web applied to both of the folder sides with the extension member secured between folded opposing adhesive portions of the web to provide a unitary labelled tab on a folder.Type: GrantFiled: June 24, 1981Date of Patent: June 18, 1985Assignee: Datafile LimitedInventor: Donald T.

Patent number: 4288170Abstract: A file binding system according to the present invention comprises a pair of elongated rigid support members for supporting a file along its edge and securing members for securing the support members in position. The support members are fully separable from one another and from the file edge with the securing members being independent of the support members other than in the securing position, thereby adapting the arrangement for use with essentially any file size. Furthermore, each of the securing members includes securing portions for securing the support members from their outer sides along the file edge. This latter feature not only facilitates binding adjustment but also provides an extremely effective clamping of the file edge between the support members.Type: GrantFiled: August 31, 1979Date of Patent: September 8, 1981Assignee: Datafile LimitedInventor: Donald T.

Patent number: 4240848Abstract: Alphabetic labelling of articles includes the use of a label having on a portion of its face a first set of indicia and on another portion of its face a second set of indicia which relate to the same subject matter as the first set. The second set of indicia is oriented in reverse and upside down relative to the first set. A machine readable code unique to the subject matter of the sets of indicia is located on one of the face portions of the label. The label when folded about its length isolates the two fields and on application to an article, provides visual identification of the article from two of its sides. The label may be provided with a machine readable indicia code which is representative of at least one indicium of either of the sets. An article labelling system may be adapted to read the indicia code and apply as controlled by the reading operation, one or more labels having letters corresponding to the coded indicia.Type: GrantFiled: July 5, 1978Date of Patent: December 23, 1980Assignee: Datafile LimitedInventor: Donald T.
