DEFINITION

Classification: 66/224

Including drum having integral plural level pattern:

(under subclass 222) Subject matter wherein the butt selection means includes a cylinder structurally provided with components at plural levels directly controlling selective engagement of butts at plural levels.

(1) Note. Included in this subclass are knitting machines with control drums provided with a flexible pattern tape which either: (a) surrounds the drum and thereby constitutes an integral part of the drum or (b) causes the tape to selectively position the components thereby transferring the pattern thereto.

(2) Note. The term "pattern" generally connotes a design array stored mechanically or electrically which is retrieved to control the formation of a fabric design.
