Abstract: The ribbon loading container and method includes an elongated housing forming an envelope and having front and rear open ends. A ribbon dam is slidingly received within the envelope of the housing and has a slot therethrough for the passage of the ribbon. The ribbon dam further includes tension clips which frictionally engage the ribbon passing through the slot and frictionally engage the sides of the housing. A drive and driven roller are rotatably disposed adjacent the open front end of the ribbon loading apparatus for introducing ribbon into the envelope. The ribbon dam is initially positioned adjacent the open end of the ribbon loading container such that it applies a back pressure to the incoming ribbon being stuffed into the envelope by the drive and driven rollers. As the envelope is filled with inked ribbon, the ribbon dam slides within the ribbon loading container until the pre-selected length of ribbon has been loaded in the container.

The article can be applied with the label while the article is being continuously transferred without being moved intermittently, whereby the apparatus can be easily operated at a high speed.
Abstract: The present invention is a portable manual tape dispensing apparatus for use with a stretchable adhesive tape such as of the type that progressively detackifies when stretched. The apparatus has a supply spool for carrying a supply of the tape and a handle connected to the supply spool for manually grasping and manipulating the apparatus. A mechanism for stretching the tape is arranged and configured to receive the tape from the supply spool. The stretching mechanism has a stretching zone defined between first and second engagement surfaces. The first and second engagement surfaces frictionally engage the tape and move at disparate longitudinal speeds to stretch the tape when the stretching mechanism is activated. A manually operative mechanism is provided for selectively activating the stretching mechanism so an operator can remove the tape from the supply in a substantially detackified stretched condition when the stretching mechanism is activated.

Abstract: Rolls of toilet paper are produced by winding a paper web around each of a plurality of air permeable cylindrical cores each having a fixed, outer diameter while applying a liquid to only a leading portion of each web so that wound webs each having a wet inner portion are formed. After drying the wound webs to integrally bind the inner portion, the core is separated from each of the wound webs.
Abstract: A label inserter and method for supply of labels to a mold of a blow molding machine for the production of in-mold labeled plastic products in which a label carrying, vertically liftable beam extending from a carriage driven by a computer controlled linear motor sets labels in the recesses of a mold as it moves into alignment for receipt of a portion of parison to be blown into the desired product. As disclosed the mold is driven along an upwardly inclined path toward the parison and the linear drive support and carriage are drawn thereby along a parallel path in unison with the mold. After insertion of labels, the beam is withdrawn for receipt of additional labels whereupon the carriage and label loaded beam are advanced to a position just outside the path of mold movement to await return and opening of the mold for another cycle of label insertion. Label holders on both sides of the insert beam swing outwardly for receipt of labels and for deposition of labels in the recessed walls of the mold.
Abstract: An apparatus and method for applying labels onto small cylindrical articles such as dry cell batteries is disclosed. A label transport drum has a substantially smooth surface. Cut labels are applied to the surface and an adhesive applicator applies a preferred cold adhesive onto an area adjacent the leading edge of the label. A solvent applicator applies a predetermined amount of solvent on the area adjacent the trailing edge of the label. The solvent applicator includes a solvent transfer roll and a rotatably supported rotary pad print head. The rotary pad print head includes at least one narrowly tapering, flexible wiper tip. In one embodiment the wiper tip has a V-notch on its end. The flexible tip engages the solvent transfer roll, transferring solvent from the solvent transfer roll into the V-notch. The rotary pad print head is timed to rotate so that the flexible tip is deflected against the area adjacent the trailing edge of the label.
