The garment sequencing programme is the most important requirement of a garment-knitting machine because it has overall control of the functioning of the machine whose automatic operation follows the specified programme.
On mechanically-controlled power flats, it is the pasteboard movement-card mechanism that provides the programme controlling and co-ordinating the machine's functions throughout the garment-length knitting sequence.
The positions of holes punched in the cards determine movement functions such as yarn carrier selection, positioning of knitting cams, needle bed racking, and overall control of the jacquard mechanism.
The cards are expensive and time-consuming to assemble, shaping programmes would require many extra cards and sequential knitting would require the equivalent of four programmes - for the front, back and two sleeves.
