Abstract: A method for spreading a textile sheet where the sheet is caused to run between at least two rotary rollers, the axes of which extend parallel to each other and substantially perpendicular to the running direction of sheet. The sheet under pressure is caused to pass between at least one pressure generator of the rollers driven into axial oscillation and in phase opposition. At least one pressure generator of the rollers has adjustable pressure values along the generator in order to spread the sheet with a low thickness variability.
Abstract: There is disclosed a device for the continuous fulling of a material web (6) of textile woven fabrics and knitted fabrics with a guiding passage (15) through which the material web (6) can be guided through and accelerated by means of a fluid. At the end of the guiding passage (15), there is provided an impact surface (16, 17), against which the material web (6) can be flung by the fluid. Between the impact surface (16, 17) and the guiding passage (15) there are additionally provided guiding means (26, 26') by means of which the material web (6), which is broadly guided in the guiding passage, can be brought together to a material strand (25) before impinging on the impact surface (16, 17).
Abstract: Each roller (7) is mounted by means of bearings (36) on a shaft beam (30) tegral with the stator (42) of the electric motor, while the rotor (50) of said electric motor extends in annular form around the stator (42) and is integral with the peripheral shell (7B) of the roller.

Abstract: In a fulling machine for textiles and the like, comprising a pair of draw cylinders (3, 4) between which the textile (T) is made to pass and means of driving said cylinders, said driving means comprise, for each cylinder (3, 4), a motor (13) disposed inside the cylinder itself with the motor drive shaft extending in a direction perpendicular to the cylinder axis of rotation. In this way a substantial reduction in the transverse dimension is obtained.

Abstract: A knitted or woven fabric in the form of a pliable sheet in fulled by having the fabric be conveyed in one direction, cooled to a temperature below the freezing point of water, impregnated with moisture and dried.
Abstract: An apparatus for fulling a knitted or woven fabric in the form of a pliable sheet includes a conveying device for conveying the fabric in one direction, a cooling device for cooling the fabric to a temperature below the freezing point, steam jet means for jetting steam against the fabric and a drying device for drying the fabric.
Abstract: A felting apparatus having an upper and a lower row of driven rollers and including compression beams intermediate any two adjacent rollers in each row whereby the compression beams in one row may be disposed opposite corresponding compression beams or opposite rollers in the other row and define together with the opposing member tapered entry apertures for the material being processed. The compression beams and/or the rollers in both rows may be spring-biased, include heating means and be adapted to be axially reciprocated by driving means.
Abstract: A device for the even, continuous impregnation of textile rope wherein at least two vertically spaced spray tubes spray impregnating liquor onto the rope which then passes to double conical shaped impregnation element disposed below the sprays; transport rollers below the impregnation element convey the rope and underneath the transport rollers, a compression compartment compresses the rope which is then passed in narrow loops around staggered rollers for fulling.
