摘要
A gripper device for transporting and registering sheets of any type under the printing heads of silk screening and the like printing machines, which comprises a box-like supporting body having hingedly connected thereto, against the bias of preloaded spring members, a plate- like element forming a flat jaw, and juxtaposed thereto, a plurality of flat surface gripper elements which are set in mutual alignment and for oscillation about a parallel axis to said juxtaposed jaw and adapted to be brought close against said juxtaposed jaw by means of at least one slide element which is driven reciprocatingly by a drive shaft from the silk screen printer, said slide element being provided with an actuating means cooperating with means associated with said flat jaw and with said plurality of juxtaposed gripper elements and adapted to produce, as said slide is being reciprocated, a rotation of said plurality of gripper elements about their own axes toward said opposed flat jaw and to allow said flat jaw to be disengaged from said slide.
