Abstract:
Redetachable, self-adhesive device having a plate, the sides and/or front side of which have fastening means, if appropriate, and the rear side of which has a strip of an adhesive film which is adhesive on both sides and is adhesively attached in such a way that one end of the adhesive film protrudes beyond the plate as a grip, the adhesive film being of such a kind that the adhesive bond achieved with it can be released again by pulling in the direction of the bonding plane, stretching the strip, characterized in that the rear side of the plate (1) has laterally alongside the adhesively attached adhesive film (5) spacers (3A, 3B), the height of which is less than the thickness of the adhesive film
Abstract:
A packaging tape includes a plastic film formed in a continuous length, and having first and second edges along the continuous length, and further having first and second portions continuously along the length adjacent the first and second edges, respectively. An adhesive is applied to both the first and second portions. Means for deadening the adhesive is applied to the first portion, whereby the first portion forms a continuous pull-tab along the length of the tape to facilitate removal of the tape. Ink is applied to the first portion for displaying tape removal instructions. A method of manufacturing the tape is also provided.
Abstract:
Use of an adhesive film which is detachable by pulling in the direction of the bond plane and a) whose self-adhesive composition is based on thermoplastic rubber and tackifying resins, the said adhesive film having high elasticity and low plasticity, the adhesion being lower than the cohesion, the adhesiveness largely disappearing when the film is extended and the ratio of peel force to tear load being 1:1.5 or more, and b) which carries an extensible nonwoven laminated onto one side of the adhesive composition, as a painter's decorative tape which can be removed again by pulling without residue or damage.
Abstract:
An article support adapted for adhering to a substrate is described. The article support preferably includes a base member, a stretch release adhesive tape adhered to that base member, and some mechanism for gripping the stretch release adhesive tape. These items are arranged so that when the base member is adhered to the substrate by the stretch release adhesive tape, the base member can be removed by pulling on the gripping means at an acute angle from the surface of the substrate. Gripping means which resist disassociation from the stretch release adhesive tape during the removal of the base from the substrate are disclosed, including handle types. The base member can be generic, suitable for attaching various types of support members via, for example, complimentary dovetail slides. In such cases, provision such as a latch can be made to temporarily lock the support member to the base member. The article support can be provided so that when the support member is removed from the base member, the gripping mechanism engages the support member to automatically stretch the tape and remove the base member from the substrate.

Abstract:
An adhesive article adapted for removable mounting on a support surface includes a stretch release adhesive tape strip and a base member. The adhesive article includes an abutment adapted to engage the support surface when the article is pressed against the support surface, and thereby prevents the base member from rebonding to the adhesive strip. The abutment thereby allows the article to be pressed against the support surface during removal to hold the article in place without interfering with the removal process. The abutment can be projections protruding from the base member on opposite sides of the adhesive strip, a pair of side walls extending longitudinally along the adhesive strip, a flexible abutment tab extending from the base member which can be manually pressed against the support surface, a projection arranged adjacent the adhesive strip which engages the support surface and acts as a fulcrum when the user applies pressure to a particular location of the base member, or a portion of an article support member which is slidably connected with the base member.
Abstract:
A removable adhesive tape comprising a highly extensible and substantially inelastic backing and a layer of pressure-sensitive adhesive. The backing has a high tensile strength, has a lengthwise elongation at break of at least about 150% with less than about 50% elastic recovery after stretching. The adhesive can be a normally tacky and pressure-sensitive adhesive and is coated on at least one surface of the film backing. The adhesive is preferably highly extensible, does not separate from the backing during stretching, and has higher cohesion than adhesion to any suitable substrate. After being applied to a substrate, the adhesive tape of the present invention becomes firmly bonded, but can be easily removed without damaging the substrate by simply stretching it in a direction substantially parallel, i.e., less than about 35.degree., to the surface of the substrate.
Abstract:
Redetachable, self-adhesive fastening device having a base plate, the front side of which serves for fastening and the rear side of which has a strip of an adhesive film which is adhesive on both sides and is adhesively attached in such a way that one end of the adhesive film protrudes beyond the base plate as a grip, the adhesive film being of such a kind that the adhesive bond achieved with it can be released again by pulling in the direction of the adhesive bonding plane, stretching the strip, characterized in that the rear side of the base plate has duct-like depressions in the region in which the strip of adhesive film is adhesively attached, these depressions extending at least partially beyond the region of the strip of adhesive film.
Abstract:
Adhesive tape for a bond which can be redetached by pulling, without residue and without damage, having a foam backing coated on one or both sides with a self-adhesive composition, characterized in thata) on at least one of the two sides of the foam backing there is applied a self-adhesive composition whose ratio of tear strength to stripping force (peel force) at a peel angle of less than 10.degree. to the bond surface is greater than 1.2:1,b) the foam backing is subjected to controlled pretreatment/damaging in such a way that the detachment force (stripping force) is lowered relative to an analogous self-adhesive tape with a foam backing which has not been correspondingly pretreated/damaged, andc) the foam backing does not have a tear strength which is sufficient for redetachment without residue or damage.
