Abstract
The fulling machine comprises a plurality of pairs of rollers in facing relation to each other and movable relative to each other and defining therebetween a passage and pinching gap. At least one of the rollers of each pair of rollers undergoes a cylindrical movement which varies both the width of the gap and the relative position of the two rollers in a direction perpendicular to the gap and to the axis of the roller. It is particularly advantageous in the fulling of felt pieces.
Claims10
A multiroller fabric fulling machine comprising a frame, a plurality of adjacent first rollers and a plurality of adjacent second rollers, the first and second rollers being mounted to rotate about their axes relative to the frame, the first rollers being arranged in pairs with the second rollers so that the first roller and second roller in each pair of rollers are capable of defining a pinching gap for the passage of the fabric being fulled, each pair of rollers being relatively movable toward and away from each other, means for rotating the first and second rollers about their axes relative to the frame, means for imparting to the axis of the first roller of at least one of said pairs of rollers a cylindrical movement which movement moves the first roller toward the second roller of said one pair of rollers and varies the relative position of the two rollers of said one pair of rollers in a direction transverse to the axis of said first roller of said one pair of rollers to superimpose periodic oscillations on the rotary movement thereof.
A multiroller fabric fulling machine comprising a frame, a plurality of adjacent first rollers and a plurality of adjacent second rollers, the first and second rollers being mounted to rotate about their axes relative to the frame, the first rollers being arranged in pairs with the second rollers so that the first roller and second roller in each pair of rollers are capable of defining a pinching gap for the passage of the fabric being fulled, each pair of rollers being relatively movable toward and away from each other, first drive means for rotating the first and second rollers about their axes relative to the frame, at least one of said first rollers being combined with a shaft mounted to rotate relative to the frame about a fixed axis, the shaft having cylindrical bearing portions which are eccentric relative to said fixed axis, said one first roller being rotatably mounted on and concentric with said eccentric bearing portions, and second drive means for rotating said shaft about said fixed axis to superimpose periodic oscillations on the rotary movement thereof.
A multiroller fabric fulling machine comprising a frame, a plurality of adjacent first rollers and a plurality of adjacent second rollers, the first and second rollers being mounted to rotate about their axes relative to the frame, the first rollers being arranged in pairs with the second rollers so that the first roller and second roller in each pair of rollers are capable of defining a pinching gap for the passage of the fabric being fulled, each pair of rollers being relatively movable toward and away from each other, first drive means for rotating the first and second rollers about their axes relative to the frame, means for mounting the axis of rotation of each first roller of said first rollers to revolve about a second axis which is fixed relative to the frame and parallel to the axis of rotation of said each first roller, the second axis and the axis of rotation of said each first roller being at a constant distance from each other, and second drive means for revolving the axes of rotation of said first rollers about their corresponding second axes to superimpose periodic oscillations on the rotary movement thereof.
