What is "Drawing" - Definition & Explanation

Operations by which slivers (q.v.) are blended (or doubled), levelled and, by drafting (q.v.), reduced to the stage of roving (q.v.) (In the cotton industry, the term is applied exclusively to processing at one machine, namely the draw frame).
Various systems of drawing are practised but, with the advent of man-made staple fibres and recent machinery development, the boundaries between the various systems are becoming less distinct. In the worsted industry, the systems differ mainly within the means of fibre control between the major pairs of drafting rollers and the methods of driving the spindles and bobbins, if these are employed.
The various worsted systems are:
a) American system (oil-combed tops).
b) Anglo-continental system (oil-combed tops). d) Continental system (dry-combed tops).
e) Open system (oil-combed tops).
f) Raper system (oil-combed tops)
The process of threading the WARP filaments from a beam through the heddles and reed of a loom in the order indicated on a design draft.
