Abstract
A process for the formation of loops freely suspended over a plurality of supporting means for the conveyance of textile material, particularly web-shaped material, which is sensitive to longitudinal tension through a treatment chamber, e.g. a steamer, slowly traversed by the supporting means, e.g. supporting rollers, supported by an endless conveying means, e.g. an endless conveyor chain includes the steps of maintaining supporting means coming into contact with the material constantly in rotation during the formation of the loops, and effecting the loop formation by the relative motion of successive supporting means with respect to one another.
Claims53
A process for the formation of loops of textile material freely suspended over a plurality of successive supporting roller means for the conveyance of the textile material which is sensitive to longitudinal tension through a treatment chamber slowly traversed by the supporting means supported by an endless conveying means wherein the supporting means coming into contact with the textile material are maintained constantly in rotation during formation of the loops of textile material, and the loop formation is accomplished by producing a relative motion between successive supporting means with respect to one another on said endless conveying means, and by providing substantially no relative motion between the supporting means and the textile material, said loop formataking place between supporting roller means rotating at different speeds and the material being supported thereon solely by friction.
An apparatus for producing loops of textile material which comprises a steamer housing including a dwell section, an endless conveyor means longitudinally traversing said housing, said conveyor means comprising two chain means respectively guided laterally within said housing, a plurality of supporting roller means for supporting and for conveying loops of textile material within said housing, said supporting roller means being transported and held laterally within said housing by said endless conveyor means, said conveyor means while moving the loops of textile material through the dwell section of the housing effecting change in position of the loops with respect to the supporting roller means, means for continuously rotating the supporting roller means coming into contact with the textile material during loop formation to effect continuous movement of the textile material over successive supporting means, said conveyor means effecting relative motion between successive supporting roller means during loop formation and said means for rotating said supporting roller means providing substantially no relative motion between the roller means and the moving textile material and including auxiliary means for causing the supporting roller means on which the loop formation take place to rotate at different peripheral speeds.
The apparatus according to claim 52, in which said take-off roll is associated with a further roll for the formation of a nip that engages said material.
