Abstract: A unit for transferring an article from one work station to another has a rotary table with an arm mounted on the table for reciprocation in a radial direction, the arm carrying an article holder at its outer end and being reciprocable by means of a cam follower coupled to the arm and engaging a stationary cam track. The arm has a radial pin engaging in a helical slot in a bearing sleeve whereby reciprocation of the arm also rotates the arm to invert the article holder.
Abstract: An object transfer machine has a carrier with separate reversible drives for vertical and horizontal motions controlled by a bank of control cams driven through a control cycle by a motor, each cam causing one of the drives to operate for a set period in the required direction.
Abstract: Glass or like stemware is manufactured in one piece by part-forming an article having a glob of material in the position where the stem is required, placing the glob between rollers which have a shape defining the required shape of the stem, and rotating the glob between the rollers while advancing the rollers inwardly. Subsequently a foot forming member is axially advanced towards the glob to apply pressure against the glob to form a radially-extending foot.
