Abstract
A textile machine segment including a first or main roller (12) adapted to support and convey a travelling fibre web, associated second (16) and third (14) rollers cooperable with each other and at respective nips (24, 25) with the first roller as the three rollers rotate, to open the web and detach a mat of fibre tufts at the nip (25) between the first and second rollers and to return the tufts to the first roller at the nip (24) between the first and third rollers, and drive means (100) for rotating the rollers, wherein the drive means is arranged to rotate the second roller in a rotational direction that is the same as that of the first roller and opposite that of the third roller.
Claims17
A textile machine segment including a first or main roller adapted to support and convey a traveling fibre web, associated second and third rollers having respective nips, with each other and with the first roller as the three rollers rotate, and drive means for rotating the rollers, being arranged to rotate the second roller in a rotational direction that is the same as that of the first roller and opposite that of the third roller, wherein the second roller is downstream of the third roller and is cooperable with the first roller to open and detach a mat of fibre and convey the mat to the nip with the third roller, the mat of fibre being there transferred to the third roller and conveyed by the third roller to the nip with the main roller where it is transferred back to the first roller, and wherein the ratio of the diameter of said second and third rollers is less than 1.5.
A method of treating a travelling fibre web, including supporting and conveying the web on a rotating first roller, and operating respective pairs of second and third rollers cooperable with each other and at respective nips with the first roller whereby to open the web and detach a mat of fibre at the nip between the first and second rollers, to convey the mat to the third roller, and to return the mat to the first roller at the nip between the first and third rollers, wherein said operation of the respective pairs of second and third rollers is effected by rotating the second roller in a rotational direction that is the same as that of the first roller and opposite that of the third roller, and wherein the second roller is downstream of the third roller and the ratio of the diameters of the second and third rollers is less than 1.5.
