Abstract: Pressure-sensitive adhesive tape is made by coating a sheet backing with a solution of iso-octyl acrylate:acrylic acid copolymer containing a tackifying rosin ester and an anti-oxidant, evaporating the solvent, and crosslinking the adhesive. The resultant adhesive has an excellent balance of the tack, peel adhesion, and shear properties, even at 70.degree. C., and adheres well to low energy surfaces.

Abstract: A hosiery repair kit includes a repair strip, textured as original hosiery material, adhesive-backed and carried in strips or a tape on a peel-off backing. The backing may be in the form of a sheet carrying several strips. As a tape, the repair material may be mounted in a dispenser which has a cutting mechanism and a take-up reel for the waste backing material.

Abstract: This is a multi-purpose, low-profile desk accessory in which a horizontally oriented flat base sheet is formed with upstanding walls which define a plurality of shallow storage wells, including one for the storage for a roll of tape which is horizontally oriented, and another for the storage of a flat stack of unbound note paper. Suitable means are provided for twisting the tape 90.degree. as it comes off the tape roll. Above these shallow storage wells are upper decks which provide additional storage space, some of which is specifically dedicated to such office implements as a ring-bound calendar, and possibly an ash tray or card file. Alongside the shallow lower level and upper level storage facilities is an elevated structure which includes deep wells for the storage of paper clips and similar desk implements, and another deep well for storing elongated writing instruments such as pens and pencils in a horizontal attitude.

Abstract: A tape package for a roll of adhesive tape having a cover element joined to a base member. A friction disc is attached to the base member and arranged to engage an end surface of the roll of tape.

Abstract: An adhesive composition which, in the preferred aspects of the invention, is a partially cured reaction product of the composition in the form of a dried, preformed film that is heat-activatable, is provided comprising in admixture a poly-functional active hydrogen containing component consisting of, in combination, a hydroxyl terminated polyurethane polyester having a hydroxyl number no greater than about 15 and a member containing at least difunctional active hydrogen having an active hydrogen equivalent weight of at least about 27 and less than about 500, a component having available free isocyanate groups, and a fourth component such as a chlorinated aliphatic hydrocarbon, a chlorinated aromatic hydrocarbon, or an alkylated polystyrene.

Abstract: A web product which is wound into a roll includes a web which is provided with at least one marker to aid a user dispensing the product. The marker extends tranversely across the inside surface of the web, and the web and marker are contrasting colors for visibility.A method of forming the web product includes the steps of providing a web, positioning a marker transversely across the web at a predetermined location, adhesively securing the marker to the web, and winding the web into a roll. The web and marker are contrasting colors so that the web can be unwound to expose the marker which signifies to a user that a predetermined portion of the length of the web has been unwound.

Abstract: A heat-tempered film element having a core-set curling tendency and a net core-set curl at least about 15% below that of a similar non-heat-tempered film element is provided by a process which comprises heating a sheet or roll of self-supporting, core-set-prone thermoplastic polymeric film, which is non-coated or is coated with one or more layers on at least one surface, under ambient relative humidity of less than 100%, at a temperature in the temperature range of from about 30.degree. C. up to about the glass transition temperature (Tg) of said polymer for 0.1 to 1500 hours, said heating being continued until the change in the number of ANSI curl units that the resulting film undergoes upon subsequent core-setting at 21.degree. C. and 50% R.H. for 2200 hours is reduced by at least 15%, compared to the change in the number of ANSI curl units untreated thermoplastic polymer film undergoes upon core-setting under like conditions.

Abstract: The apparatus and method of the present invention is adapted to be utilized with respect to packages of connected forms of the type having sprocket holes along the margins thereof which are adapted to be engaged by sprocket wheels in, for example, a print-out device for advancing the forms to an operating station in the device. The method comprises providing a strip having sprocket holes therein. The spacing of the sprocket holes on the strip is equal to the spacing of the sprocket holes on the forms. The strip is connected to the first form of the package with the sprocket holes in the strip in alignment with the sprocket holes in the margin. The strip or strips are then engaged with the sprocket wheels in the device which is then operated to advance the package of forms into the device.

Abstract: A tape applicator including a frame with a rotatable mandrel for mounting one or more rolls of adhesive tape, the frame including a flat, elongated portion under which the tape passes and which acts to apply the tape positively and firmly to a selected surface as the applicator is moved thereover, and the frame further including guides at the location of the elongated portion through which the tape passes to insure accuracy in application and equidistant spacing between multiple tape strips. The guides also act as means for removing any tape lining as the tape is applied. The applicator is designed for one hand operation and is disposable, being constructed of inexpensive materials with the frame preferably formed from a flat cutout of paperboard or the like.

Abstract: A packaging container blank comprising a rectangular central section including at least one tab therein which is hinged on one edge to the central section, the remaining edges of said tab being severed from said central section. Two outer panels are attached to opposite peripheral edges of the central section, and two flange panels are attached to the other opposite edges of the central section. The blank is adapted to be folded into the form of a container.

Abstract: A roll of a continuous strip of a non-woven fabric having on only one side thereof a heat actuatable adhesive, said fabric having at least one longitudinally running perforated line running parallel with a side edge of said fabric, said fabric being free of any surface interruptions other than perforated lines running parallel with a side edge and its use in garment manufacture.

Abstract: Release agents are provided which comprise the polymeric reaction product of a fatty diamine with a diisocyanate and, optionally, a diol. These polyurea and polycarbamate products have the following recurring formula: ##EQU1## WHEREIN A is an alkylene radical containing about 2 to 6 carbon atoms, B is an arylene radical containing about 6 to 16 carbon atoms, D is an aliphatic organic radical containing about 2 to 6 carbon atoms, R is an alkyl radical containing about 12 to 25 carbon atoms, R' is hydrogen or an alkyl radical containing about 1 to 25 carbon atoms, a and b represent the number of recurring units and the ratio of b/a varies from 0 to 2, and c is 0, 1 or 2. Also provided are pressure sensitive adhesive tapes and release liners utilizing these novel release agents.
