ABSTRACT:
The machine comprises essentially a substantially belt-like endless conveyor provided with plates having cells to which the bodies to be wrapped are supplied individually. The cells with the bodies housed therein are covered by a wrapping sheet which is supplied continuously and is subsequently cut to form an individual wrapping sheet portion for each body. The unit constituted by each body and its respective wrapping sheet portion is turned over and transferred by a thrusting action exerted on the body to a drum provided with gripping jaws and associated folding members. An intermediate, generally tubular wrapper with two end parts and a central part in which the body is situated is thus formed. The two end parts are acted on by rotary pincers provided with pairs of clamping fingers for forming bow-like twists in the ends.
The preferred application is for wrapping food products such as sweets and the like.
