Abstract

L'invention concerne une bande de nettoyage, en particulier pour tête magnétique d'appareils d'enregistrement et/ou de reproduction. Selon l'invention, ladite bande est constituée d'un support en polyester et d'au moins un film de matériau non tissé contrecollés. Selon une variante de réalisation, ladite bande comporte un support en polyester disposé en sandwich entre deux bandes de matériau non tissé. On réalise ainsi le nettoyage des têtes magnétiques et des moyens d'entraînement de la bande. Application : cassettes de nettoyage pour magnétophones.The invention relates to a cleaning tape, in particular for a magnetic head of recording and / or reproducing apparatus. According to the invention, said strip consists of a polyester support and at least one film of laminated nonwoven material. According to an alternative embodiment, said strip comprises a polyester support sandwiched between two strips of non-woven material. The cleaning of the magnetic heads and the tape drive means is thus carried out. Application: cleaning cassettes for tape recorders.
