PCT No. PCT/GB82/00056 Sec. 371 Date Sep. 30, 1982 Sec. 102(e) Date Sep. 30, 1982 PCT Filed Feb. 22, 1982 PCT Pub. No. WO82/02876 PCT Pub. Date Sep. 2, 1982.An individual section glassware forming machine comprises generating means (29) for generating an electrical command signal which is used to control transfer means (2) of the machine. The transfer means (2) is used for transferring a parison (P) from a blank station (A) at which the parison is formed in an inverted position and presenting the parison (P) in an upright position at another station (B). The magnitude of the electrical command signal varies in accordance with the desired position against time curve for the movement of the parison (P) and is used to operate an electrical or hydraulic servo-mechanism (32; 42) for controlling the movement of the transfer means (2).
