Abstract: In a preferred method for affixing a discrete paper label to the mailer, a discrete paper label is suctioned onto the rotatable platen at a first predetermined position relative to the circumferential perimeter of the platen. As the rotatable platen rotates, adhesive is applied to a predetermined exposed portion of the paper label at a second predetermined position relative to the circumferential perimeter. Finally, at a third predetermined position relative to the circumferential perimeter, the paper label is blown off the rotatable platen and onto an adjacent continuously advancing web comprising multi-ply mailer forms each having a plurality of sheets in superimposed relationship. The paper label is thus affixed to a multi-ply mailed form at a predetermined location. Preferably, the rotatable platen receives a new paper label at the first predetermined position as the adhesive is applied to the label previously received on the platen.

Abstract: Magnetic stripes are applied to magnetically readable credit cards by incorporating the magnetic stripes in a cover sheet and laminating this cover sheet to a core stock sheet and then severing the laminated assembly into individual cards. The magnetic material bearing cover sheet is made by feeding the cover sheet without stripes continuously through a nip along with a plurality of tapes. Each tape is a laminate originally including a release layer, a magnetic layer, an adhesive layer, in that order, on a carrier layer. Heat and pressure applied to the nip releases the magnetic layer from the carrier layer and activates the adhesive layer to bond the magnetic layer of each tape to the original cover sheet, thus forming a stripe on the cover sheet. Distortion of the cover sheet by substantial shrinkage or wrinkling due to the heat effects resulting from the bonding operation are effectively eliminated by the use of a chill roller.

Through tensioning, the hybrid band is pre-stressed before feeding the pre-stressed hybrid band to the paper forming screen roll, sensing the position of the hybrid band on the paper forming screen roll, sensing the position of the hybrid band on the paper web, and regulating and controlling the positioning of the hybrid band through the adjustment of the tensioning in accordance with the position of the hybrid band in the paper web.

Abstract: A fiber wallboard, or similar rigid or non-rigid substrate, is directed via a conveyor through a roll coater for providing an adhesive layer on one side of the substrate. Packages of continuous strands, such as textile yarns, are supported on a yarn creel, and drawn through expansion combs and underneath a nip roll for being press rolled into the adhesive coating layer. The pattern of lateral yarn separation established with the expansion combs creates a particular design on the finished face of the substrate, and may be varied. The substrate with applied strands is dried and trimmed. Marginal edge yarns are particularly located relative the substrate edges so that yarn gaps surround seams between adjacent panel substrates. Seaming tape with additional textile yarns supported thereon may be fitted in the gaps to hide such seams.

Abstract: Double sided optical memory disks are produced by dropping a viscous adhesive material hardenable by ultraviolet radiation at predetermined longitudinal intervals onto an elongated cloth material of uniform thickness thereby causing the adhesive material to become absorbed by and contained in the cloth material, thereafter placing this cloth material sandwichedly between two optical disk pieces each containing a recording layer, thereafter applying pressure between these pieces such that the sandwiching pieces remain separated uniformly by a predetermined separation distance, and thereafter applying ultraviolet radiation to and thereby hardening the adhesive material while the disk pieces are maintained at the uniform separation distance.

Abstract: A cable shielding tape is produced by laminating a single layer of an insulating material film which may be plastic to a conducting layer which may be of metallic foil with one edge of the conducting layer offset laterally with respect to said insulating layer, leaving a foil free edge portion of the insulating layer along one edge of the tape. This can be manufactured by laying the insulating layer tapes in a shingled formation, laminating a web of foil over the tapes and then separating the tapes each with a partial covering of the foil. The conducting layer and insulating layer are coterminous at the opposite edge and both are folded back with the conducting layer outermost.

Abstract: This invention concerns an improved gluing machine and a continuous method of operation which allows the gluing process to proceed at a rate that equals the feed rate of vacuum rotary document feeders. The machine includes a unique registry and guide system for efficiently moving documents fed initially in an individual manner in a continuous, flowing manner from an initial input feed device to the gluing and registry point with the carrier. The feed system not only allows substantially greater operating speeds but simultaneously overlaps documents while establishing and maintaining correct registration of the documents. The documents are overlapped so that following documents are positioned beneath leading documents. This overlapped condition together with the registry achieved within the feed system assures each individual document arrives in proper registry with areas of glue previously applied at preselected intervals on the carrier sheet.
