Thefeeding line 2 is made up for example of a conveyor belt on which the confectionery products, for simplicity not represented, are fed in succession in support on a flat lower face. The feeding line can be anyway be made up of transport means having a different shape, in particular provided by suitable separation means for the products, provided with containment seats for the product or with separation means for the same products, in a manner known per se. - At the exit from the conveyor belt of the
feeding line 2, asupport member 4 is arranged, attached to the framework of the wrapping machine and suitable to be an extension of the same feeding line. A stoppingmember 5 cooperates with thesupport member 4 and is suitable to hold the single products in a pre-established position, substantially corresponding with a picking position by means of the feeding device 1. The stoppingmember 5 is carried protruding frontally to thefeeding line 2 by means of alever 6 tilting about a pivot 7.

jaws levers support member 4. Obviously, it is possible to provide that the product to be wrapped be arranged in the picking position by thegrip member 13 through members of different type, such as for example an overturn member for the same product. - Subsequently, the tilting of the
arm 11 which carries thegrip member 13 is operated, to transfer the product gripped between thejaws lift 31 and the counter-lift 32 of thelift unit 30. - At the same time, the
rocker arms levers grip unit 13, to cause a corresponding angular rotation of thejaws figure 3 ). Suitably, such angular rotation extends for an arc of 90°. In such way, the product to be wrapped reaches the release position being shifted on a vertical plane parallel to the picking plane, outgoing from thefeeding line 2. - Once arrived at the release zone, the product is wrapped at the top by the wrapping sheet.

This is due essentially to the presence of the transfer and orientation unit suitable to tilt on the vertical plane parallel to the plane of the wrapping head and simultaneously to turn the orientation of the products gripped by the jaws associated with the tilting arm of the above mentioned transfer and orientation member.
- Therefore, the transfer and orientation member according to the invention allows to perform in an optimal way the transfer and the rotation of the products, thus totally preventing to obstruct the front zone of the wrapping machine.
- A feature of the invention consists in the fact that the transfer and orientation member allows to transfer and to turn the products to be wrapped from the picking zone to a release zone suitably spaced, at which the lift means operate to feed the same products to the wrapping head of the machine. This allows to free a suitable space under the wrapping head, between the picking zone and the release zone, to allow an optimal housing of the feeding means for the wrapping sheet and to prevent the storage of different working members of the machine.

In particular, the time required by the transfer and orientation unit for completing a transfer cycle can be optimized according to the time required to divide and arrange a new product on the picking position.
- It is to be observed that the kinematic means and the actuation means of the transfer and orientation unit can obviously be made in shapes different from the one described as an example, for example by using suitable gears, belts and the like.
- Finally, it is to be observed that the device according to the invention can obviously be shaped and used for any type confectionery product, in particular of any shape and size.
- A further advantage of the device according to the invention is made by the constructive compactness which allows, in a very reduced space, to house the members provided for the transfer and for the kinematic control of the product up to the wrapping head.
