ABSTRACT:
A tape laminate comprising a support layer having first and second parts, and an anchor portion of one of its opposite major surfaces on each of the parts. The first and second parts of the support layer are disposed with the anchor portions on opposite sides of the support layer and in generally parallel relationship. The anchor portions can be bonded to the opposed surfaces of rigid objects so that the tape laminate supports one object from the other against a static force generally parallel to the anchor portions. One of those bonds is made by an attachment strip having a portion of its outer major surface defined by pressure sensitive adhesive and its inner major surface bonded to one of the anchor portions, and a manually engageable tab portion at one end. The attachment strip is stretchable by pulling its tab portion to release adhesive engagement of its outer major surface from an object to which it is adhered. The first and second parts of the support layer can be torn apart or pivoted away from each other to afford separation of rigid objects to which the anchor portions are bonded, thereby affording access to that tab portion and separation of the attachment strip from one of the rigid objects by stretching the attachment strip.
