Machine for transfer pattern printing of a textile web, said machine comprising a centre roller (1), at least one pressure roller (2), a tension roller (3), a reversing roller (4) and an endless belt (5) which is of a width substantially corresponding to the length of the pressure roller (2). The endless belt (5) extends about the tension roller (3) and the reversing roller (4), and a first portion (8) of the periphery of the pressure roller (2) abuts and exerts a pressure on the centre roller (1). While in continuous contact with one another, a pre-printed pattern-carrying web (6) and the textile web (7) can pass between the centre roller (1) and the pressure roller (2) and here be subjected to a local compression. The endless belt (5) is guided around a second portion (9) of the periphery of the pressure roller (2), said second portion being positioned substantially diametrically opposite the first portion (8) of said periphery of the pressure roller, whereby the pressure exerted by the pressure roller (2) on the centre roller (1) is adjustable by an adjustment of the tension in the endless belt (5) by means of the tension roller (3).

L'invention concerne une machine d'impression à transfert de modèle d'une bande textile, comprenant un cylindre central (1), au moins un cylindre de pression (2), un cylindre tendeur (3), un cylindre réversible (4) et une bande sans fin (5) dont la largeur correspond pratiquement à la longueur du cylindre de pression (2). La bande sans fin (5) s'étend autour du cylindre tendeur (3) et du cylindre réversible (4). Une première partie (8) du pourtour du cylindre de pression (2) vient buter contre le cylindre central (1) sur lequel il exerce une pression. Une bande porteuse (6) de modèle réimprimé et la bande textile (7) peuvent passer entre le cylindre central (1) et le cylindre de pression (2), lorsqu'elles sont en contact ininterrompu et peuvent être soumises à une compression locale. La bande sans fin (5) est guidée autour d'une seconde partie (9) du pourtour du cylindre de pression (2), cette seconde partie (9) étant placée pratiquement face à la première partie (8) du pourtour du cylindre de pression dans un sens diamétral. Ainsi, la pression exercée par le cylindre de pression (2) sur le cylindre central (1) peut être réglée par un réglage de la tension de la bande sans fin (5) à l'aide du cylindre de tension (3).
