ABSTRACT:
An adaptor for a suction pipette of a machine for picking up, transferring and placing components in a desired position characterized by the adaptor having a base member with a socket receiving a movable ball member. The ball member has a surface surrounding a passageway forming a suction surface for engaging the component. The passageway of the ball member is in communication with a passageway of the base member which, in turn, is in communication with the pipette so that a suction is applied therebetween and the ball member is movable to provide a tilting of the suction surface until a component is engaged thereon, at which time atmospheric pressure acting on the ball member will force the ball member into the socket to hold the member in its selected position.
