Functions of Draw frame or Drawing

Carded Slivers are fed into the Draw-Frame and are stretched/Straightened and made into a single sliver. Also, fibre blending can be done at this stage. The cans that contain the sliver are placed along the draw-frame feeder rack, usually including eight pairs of cylinders (each pair is above the space occupied by a can),the lower cylinder is commanded positively, while the upper one rests on the lower one in order to ensure movement of the relative sliver that runs between the two.
