CA 2297461

The invention relates to a mechanical fastening element comprising a multiplicity of flexible hook elements emanating from a backing layer (1) and comprising stems (2) terminating in hook heads (3), said fastening element being releasably engageable with a complementary mechanical fastening element, the top portions of the hook heads (3) and/or at least part of the interstitial spaces (4) between the stems (2) of said fastening means being coated with a hot-melt pressure-sensitive adhesive (5) so that the level of the adhesive in the interstitial spaces (4), where present, does not exceed the length of the stems (2), and so that essentially no adhesive bridges are present between adjacent hook heads (3), said hot-melt pressure sensitive adhesive (5) having a viscosity as measured at the coating temperature of between 2,000 and 18,000 mPa-s.

L'invention concerne un élément de fixation mécanique comprenant une multiplicité d'éléments crochets souples sortant d'une couche de support (1) et possédant des tiges (2) se terminant en têtes de crochets (3), ledit élément de fixation pouvant être accroché de façon détachable à un élément de fixation mécanique complémentaire, soit les parties supérieures des têtes de crochets (3), soit au moins une partie des espaces interstitiels (4) entre les tiges (2) desdits éléments de fixation étant revêtues par un auto-adhésif (5) sensible à la pression fondu à chaud, de sorte que le niveau de l'adhésif dans les espaces interstitiels, quand ledit adhésif est présent, ne dépasse pas la longueur des tiges (2) et qu'aucun pont adhésif n'est présent entre les têtes de crochets contiguës (3), ledit adhésif (5) possédant une viscosité mesurée à la température de revêtement entre 2.000 et 18.000 mPa-s.
