DESCRIPTION:
BRIEF SUMMARY
The invention relates to the technical sector of casing. In order to understand the aim of the invention, it is necessary to recapitulate the development of the casing preparation technique on the nozzle before the hose filling operation by referring to FIGS. 1 to 6.
Initially, the casing was presented in salted masses, then brine thus enabling a saving in time and better sliding in order to slip the casing over the nozzle. The casing was generally presented folded in concertina form lengthwise, thereby using, in particular, a tube acting as an internal support.
According to this implementation the casing can be transferred from the tube to the nozzle directly. It is also possible, in order to obtain large lengths of casings, to insert a plurality of sections of casings folded and partially overlapping.
According to a non-limitative example illustrated in FIG. 1, the tube is made in the form of a flexible sheath (1) generally made of plastic, closed at one end. Therefore, in order to mount the casing, a rigid support (2) is used, around which the sheath (1) is engaged (FIG. 2). Then the casing (3) is mounted on the sheath (1) by introducing the water or brine in order to facilitate the sliding (FIG. 3). In order to position the casing on the nozzle (C), the sheath is then slipped over it (FIG. 4), then the sheath is removed thereby retaining the casing which is placed on the nozzle, thanks to an operation to hold the casing.
Then the filling and forming of sausages and saucissons or similar products, is carried out.
In practice, these operations are long and tedious. Besides, a certain fragility of the sheath when it is mounted on the nozzle is found.
In order to try and overcome these disadvantages, according to the prior art, it was proposed to insert a rigid tongue associated to the sheath in order to facilitate the mounting. The tongue is removed from the rear and the sheath from the front during use. However, this operation is somewhat impractical.
It was also proposed, in Patent FR 2.462.871 to provide the sheath (5), particularly with a longitudinal pre-cut (5.1) and place the assembly of different sections of casings on the nozzle then remove the sheath (FIG. 5). Therefore, during mounting on the nozzle, you just have to extend the movement to the rear by holding the casing with two fingers in order to tear and discharge the sheath (FIG. 6). This process avoids having to change the folding directions, enables mounting in one single action and in the case of overlapping sections of casings, prevents them from being undone, since the tensile strength applied to remove the sheath, compresses the concertina type folds in the mounting direction. However, this technique does have certain disadvantages. Firstly, the sheath diameter must be close to the size of the casing. Furthermore, as the casing is practically sealed, with the exception of the pre-cut line which defines microperforations, it is difficult to soak the casing before use. Therefore, all the current casing preparation techniques with a view to filling, do have certain disadvantages.
Another disadvantage related to all the prior techniques, lies in the fact that it is necessary to add a sheath every time the quantity of casings placed on the sheath and nozzle has been used up. In practice, and according to the techniques used, there may be a need to add a sheath every 18 to 20 metres of casing, which calls for numerous handling operations.
The aim sought after by the invention was therefore, to offer a new, simple method, easy to implement and capable of possibly entering within the framework of automated production.
According to a first characteristic, the process according to the invention is characterised wherein it enables the use of a support means acting as a sheath, previously in the form of a flat sheet, cut to shapes and sizes to be obtained, the said support means forming a sheath being put into a tubular shape by one or several deformations and successive rolling up operations with slight overlapping of its longitudinal edges, the
