摘要

Machine for blowing containers from a preform previously by injection, of the type in which a molding unit (14) comprises a mold (16) into two parts, which are cover respectively one part of a carrier mold (18) and delimiting a cavity in which, when the molding unit is open, the preform (21) is carried by at least one transfer arm (24), of the type in which the container comprises a built handle (50), one of whose connection zones (51), at least, is inserted inside the cavity (17) to be molded, during blowing, the material of the preform (21), and type comprising at least one gripping device (42) suitable for attaching a handle (50) by a gripping zone (58) to bring it from a feeding unit (66) to the mold (16), which device grip (42) of handle is carried by the transfer arm (24) of preforms being provided between elmolde (16) and the holder (18) mold cavity (60) which is adapted to receive the gripping device (42) during closing of the mold unit (14) and allowing release the gripping device (42) of the molding unit (14) upon closure thereof, axially opening cavity (17) delimited in the mold (16), so that an open end of the preform (21) protruding axially beyond a transverse face of the mold (18), wherein the recess (60) is open axially towards said transverse face of the mold (16) to allow release said direction of the gripping device (42) grips.
