(54) Hydraulic control circuit for a fabric treatment jigger


(57) Hydraulic control circuit for a Jigger type fabric treatment machine (10) where a roll (20) of fabric (18) is unwound by an uncoiler reel (14 or 16) and where the fabric itself (18) is guided into a tank (12) containing a treatment bath, before being rewound on a coiler reel (16 or 14) to form a roll (21) of treated fabric (18) and vice versa, the reels (14, 16) being operated by hydraulic motors (24, 26) connected via branches (34, 36; 34', 36') of the hydraulic circuit to a pump (28), where the hydraulic circuit is of the closed type, a brake valve (40) being also provided which exerts a variable back pressure on the motor during braking (24 or 26).
