Abstract
A drawing machine having a drawing zone (8) for drawing slivers (2), and a plurality of flyers (14) for winding the slivers on to bobbins (16), is made compact by arranging the flyers substantially longitudinally of the paths of the slivers through the drawing zone, e.g. in echelon formation with respect to the sliver paths.
Claims3
A drawing machine having a drawing zone for drawing slivers, and a plurality of flyers for winding the slivers on to bobbins, which comprises two bobbin carriages each bearing spindles which can support bobbins for rotation thereon, and means for moving the bobbin carriages, arranged side-by-side, in a direction generally at right angles to the paths of the slivers through the drawing zone, between positions in which at least one bobbin carriage is below the flyers, to enable the slivers to be wound on to the bobbins thereon, while the other bobbin carriage is displaced to one side of the flyers, to enable full bobbins to be doffed and replaced by empty bobbins, the drawing machine further comprising automatic bobbin lifting means arranged on guide supports so as to be moveable from one side of the flyers, from which full bobbins have been doffed, to the other side, on which full bobbins are to be doffed.
