  • Patent number: 4702948
    Abstract: The self-adhesive tape has two sides, one of which forms a bottom side at which a supporting or carrier fabric is only superficially covered by a contact adhesive coating. At the other side, which forms the top side, a contact adhesive coating uniformly covers the supporting or carrier fabric so as to essentially form a plane which uninterruptedly engages a separating paper layer. Due to the crossing or intersection points formed by warp and weft threads of the supporting fabric such supporting fabric produces unevenness only at the bottom side, resulting in a smaller adhesive capability or action of the lower contact adhesive coating as compared to the adhesive capability or action of the upper contact adhesive coating uniformly engaging the separating paper layer. Through the apertures or openings formed in the supporting fabric these adhesive layers are interconnected which promotes the non-separability of the self-adhesive tape as a whole.
