A pressure-sensitive tape substrate is coated with an adhesive, and the adhesive is then printed with an ink or the like that acts as an adhesive-inhibiting masking or barrier along one or more continuous zones or lines. Tapes are formed in whole or in part by slitting along the continuous line or lines so defined. The technique is used to make transfer tapes, diaper fastener tabs, and other products.

Topcoated adhesive

A stretchable tape includes a nonextensible layer having a separation line, a pressure-sensitive adhesive layer, an extensible layer and an adhesive inhibiting masking between adjacent portions of the extensible layer and adhesive layer to enable relative movement and tape stretchability. The tape is especially useful in the manufacture of diaper tabs. The tape stock and diaper tabs may be manufactured using conventional web processing equipment.

Stretchable tape

There is provided a method of dispensing telephone cards from automatic teller machines (ATM) and card constructions used therewith. Telephone time is apportioned to a number of sheetlets printed with random numbers which serve as a personal identification number (PIN). They are packaged in bricks and activated when installed in an ATM or when dispensed. The sheetlets are capable of being dispensed like currency and may contain the PIN on a removable zone.

ATM phone card system

A release liner providing a release surface which comprises a first olefin polymer film formed having dispersed therein by high shear mixing a release substance which is polyethyleneimine octadecyl carbamide, polyvinyl octadecyl carbamate or a mixture thereof, coextruded or cocast onto a film formed from a second olefin polymer. The release liner has particular utility in diaper tape application.

Release films formed by coextrusion

A refastenable diaper is provided with a securing zone on the diaper outer cover of a peak strength of less than 2750 grams/inch. A refastenable adhesive taping system for the diaper includes an adhesive fastening tape comprising a flexible backing and a layer of pressure-sensitive adhesive permanently combined to said flexible backing and adapted to be applied to and released from the securing zone to fasten and open the diaper. The adhesive exhibits a 180.degree. peel adhesion of the tape to the securing zone that is less than the peak strength of the securing zone. The adhesive is selected to be within a specified rheological window, that is, have a maximum tan delta, or (tan delta).sub.max, of from 1.5 to 2.5 at 20.degree. C., reached at a frequency, or (w).sub.max, of greater than 500 rad/sec.

Refastenable adhesive taping system

Tabless adhesive fasteners are provided for diapers. In one aspect of the invention, one face of each adhesive fastener is permanently bonded to the diaper assembly proper at an associated permanent-bond area of the diaper assembly proper at one of the two lateral sides of the diaper assembly proper and adjacent the periphery of the diaper assembly proper. The other face of each adhesive fastener is releasably carried by liner or tape protective means carried on an area of the diaper assembly proper which is offset from such associated permanent-bond area. In another aspect of the invention, the adhesive fasteners include an adhesive layer which penetrates the water-permeable inner layer of the diaper assembly proper and adhesively interacts with the water-impermeable outer layer of the diaper assembly proper, whereby such adhesive layer and inner and outer diaper layers cooperate to provide a reinforced fastener base. Each adhesive fastener may comprise two adhesive layers with a carrier layer between them.

Tabless diaper with a multi-component tape fastener

A process of making backed, pressure-adherent carpeting. A construction is assembled comprising a backing-film and an adhesive on one side of the backing film, and then, in a separate step, the other side of the backing film is heat-laminated to a web of carpeting to thereby reinforce the carpeting and provide it with an adhesive. The carpeting is both reinforced and rendered adherent in a single pass of the carpeting and at a single station in the carpet-manufacturing line.
