ABSTRACT:
A drive system for a weaving loom includes at least one four-pivot three-link drive or preferably two such drives for transmitting drive power from a main loom shaft through a cam drive to a slay shaft coupled to the cam drive through the four-pivot three-link drive. The use of two four-pivot three link drives permits operating the weaving loom selectively for producing terry cloth and/or smooth fabric. Each of the four-pivot three-link drives (DL, DR) has four pivots or journals (A, B, C, D) and three links (24, 38, 43; 25, 40, 44). Each four-pivot three-link drive cooperates with a roller carrying cam follower (15) that is controlled by an eccentric cam assembly (7). Both four-pivot three-link drives effectively operate the slay shaft (46) of the loom. A control and engagement mechanism (33, 54) provides for the switching from one four-pivot three-link drive to the other and vice versa, whereby a switch-over from the production of one type of fabric to the other is facilitated.
