Abstract: There are provided curable anaerobic pressure sensitive adhesive stocks in the form of sheets and tapes in which the adhesive is contained between two differential release surfaces. This construction permits total pressure sensitive adhesive transfer to a substrate which is to be firmly secured to another substrate upon the exclusion of oxygen and initiation of cure of the anaerobic resin.The compositions are those, based on the total weight of the composition, containing from about 4 to about 40 percent by weight of a first anaerobic resin having a viscosity up to about 1000 cps at 25.degree. C from 0 to about 80 percent by weight of a second anaerobic resin having a viscosity greater than about 1000 cps at 25.degree. C, from about 9 to 95 percent by weight of a thermoplastic resin system, from 0 to about 10 percent of a latent accelerator and about 0.1 to about 10 percent of a hydroperoxide catalyst, the composition having static shear at 0.25 in.sup.

Abstract: A label, ticket and tag printing and dispensing machine with readily detachable and attachable interchangeable tape supply and feeding magazines, for the optional and selective use of any one of several alternative pre-adjusted tape-feeding magazines, each loaded with a roll of a different size or kind of labels, tickets or tags, thereby to provide maximum and ready variability and range of tape-supply; with each of the several alternative magazines being individually pre-adjusted for the length and width and other characteristics of the label, ticket or tag and in relation to location of the print-impression of the printer. Each magazine holds a roll of labels, tickets or tags and includes a self-contained tape-feeder for intermittently feeding the tape from the roll in the magazine in label, ticket or tag lengths in timed relation to the printing sequence of the printer portion. The printer portion includes a tape-feeder cam or several alternative tape-feeder cams.

Abstract: A web construction of reclosable tab stock, particularly suited to low cost production and to high speed dispensing on automatic equipment by diaper manufacturers, but usable in other applications, has three substrates, one over the other, and each of which extends, transversely to machine direction and along its entire transverse length, substantially flatly and without folds.

Abstract: An undersurface imprintable label construction includes at least a translucent film having a layer of adhesive applied to a portion of its undersurface. One or more non-adhesive indicia-receiving zone(s) are on the undersurface of the film to form translucent window(s) on the film. A pressure-sensitive adhesive layer surrounds the window(s) and is releasably secured to a release liner which contains an indicia-transferring layer, such as a reverse carbon paper sheet, facing the undersurface of the film window(s). The undersurface of the film window area being disposed adjacent the indicia-transferring layer in the release liner allows visual indicia to be transferred from the indicia-transferring layer and imprinted on the undersurface of the window area(s) in response to pressure impact being applied to the upper surface of the film window area(s). The undersurface of the film may be partially masked to make the label substantially tamperproof.
