Abstract

Sheets (24) (e.g. of sponge cake) are placed end-to-end on a conveyor belt (10) which passes through a tubular former (20)50 that it and the sheets are rolled up, the lateral sides of each sheet being butted together. The sheets may receive a filling (e.g. ice cream) as rolling commences. After the former (20), the belt flattens out again but the items remain as filled tubes, the cake adhering to the ice cream. Other applications of the apparatus are to sausage rolls, shaping plastic sheet, or for shaping a cone of mouldable material. <IMAGE>

Description

PRO WCTIOX OF TUBULAR ARTICLES The present invention is concerned with the production of tubular (or at least part-tubular) articles, particularly food articles in which an edible tubular or part-tubular casing (e.g. of cake or pastry) contains a filling (e.g. of ice cream or sausage meat).
An example of such a food article is a style of frozen cake which is a cylinder of ice cream within a tube of sponge cake. Certain methods are not continuous and are relatively slow and labour intensive.
Broadly, the present invention arises from the realisation that, contrary to conventional wisdom, a portion of a conveyor belt can be rolled over on itself transversely while conveying, so that conveyed items are also constrained to be rolled or deformed.
According to the present invention in one aspect there is provided apparatus for the production of tubular (or at least part-tubular) articles comprising a conveyor belt having a conveying run, and a former through which the conveying run extends and which is arrayed to cause a portion of the run to curve over on itself in a transverse sense so as to define an at least partly tubular cavity. Preferably the former causes the run portion to define a complete tube, preferably with some overlapping of marginal regions. Means for feeding filling into a tubular or part-tubular article as it is formed Ray be provided adjacent the former, suitably having an outlet nozzle extending axially towards the interior of the former from the upstream side thereof.
In a second aspect the invention provides a method for the production of tubular (or at least part-tubular) articles comprising providing a portion of sheet material on a moving conveyor, and causing the portion of the conveyor carrying the sheet material to curve over on itself in a transverse sense so that the sheet material is given a tubular or part-tubular cross-section.
Preferably a filling is passed into the interior of the tube or part-tube as it is formed. The article may be a food product. Preferably the sheet material adheres to the filling, which may also be shaped by the passage through the former, to assist the article in retaining its tubular or part-tubular shape.
In a third aspect the invention provides a tubular or part-tubular article when produced by an apparatus or method according to the previous aspects.
An embodiment of the invention will now be described in greater detail with reference to the accompanying drawings in which: Fig. 1 is a schematic perspective view of an apparatus embodying the invention; Fig. 2 is a like view showing the operation of the apparatus (the drive means being omitted); Fig. 3 is a traverse section through the former in Fig. 2; Fig. 4 is a side elevation of apparatus embodying the invention applied to the production of sausage rolls; and Fig. 5 a, b, c and d show tubular articles in tranverse section.
Fig. 1 shows a generally conventional conveyor belt assembly having an endless belt 10 passing over a driving roller 12 (driven by a motor 14) and a driven roller 16, so as to be drivable in the sense of the arrows A. The upper run 18 of the belt extends horizontally, and serves as the conveying run. The belt 10 is of conventional material, having 1% stretch on total full load.
Unconventionally, an intermediate portion of the conveying run passes through a tubular former 20 which is rigidly supported, and which constrains the belt to curl over on itself tranversely, following the inner surface 22 of the former 20. The illustrated former is shaped and dimensioned so that the portion of belt 10 within it is constrained to form a complete circle with some overlap, as can be seen in Fig. 3. The former may be of stainless steel. In a practical example the normal width of the belt was 9 inches (230mm) and the overlap was 3/8 inch (9.5mm). As shown in Fig. 2, flat items 24 (e.g.
portions of sponge cake) are loaded onto the belt at the upstream end, so as to extend across most of the width of the belt, leaving a small gap at each side. They may be discrete portions 24a, 24b, 24e etc., preferably in abutting relationship as shown (particularly if they are to be filled), or a continuous web for subsequent cutting. As the belt 10 approaches the former 20 it starts to curve in the transverse sense. Within the former, the belt is fully circular with a slight overlap, as shown in Fig. 3. The width of the items 24 was selected so that their edges are brought into abutment thereby. They may be arranged to have a mutually adhering property. However, in most cases the tubular product 26 is filled as it is formed. Thus a semisolid filling 30 is extruded onto/into the items 24 just upstream of the former 20, as they begin to curve.The extruder nozzle is represented schematically in Fig. 2 by the arrow 28. The filling 30 (e.g. slightly softened ice cream) is fed in at a rate such that it fills the rolledup items 24, and is formed into a cylinder by the passage through the former. The overlap of the belt within the former protects the former from contamination by the material fed through, particularly any leaking filling. As the items 24 are rolled around the filling (which is becoming cylindrical), they adhere to it. Thus when the belt 10 leaves the former 20 and uncurls, the products 26 remain as filled tubes.
Figs. 2 and 3 show #pparatus embodying the invention applied to the production of ice-cream filled sponge cakes. Fig. 4 shows a sausage roll production line including a similar conveyor/former assembly. In this case the item 124 to form the outer tube is a continuous strip of pastry extruded onto the conveyor 110 by a pastry mixer-extruder 150. The filling 130 of sausage meat is mixed and passed into the pastry just upstream of the former 120 by a blender/extruder 128. Passage through the former 120 gives a continuous tubular product 126 which passes onto a faster exit conveyor 152 via a cutter 154 arranged so that the acceleration separates the cut-off product portions, which may then be baked.
In general, differently shaped formers can be used to give differently shaped products. Figs. 5a, b and c show examples of approximately elliptical, curvedtriangular and curved-square cross-sections. A shape with markedly re-entrant curves as shown in Fig. 5d may not be practicable. Non-closed curve sections can also be produced, eg. by passing a half-width item along the Fig. 2 apparatus.
The invention is suitable for shaping flat sheets of frangible or plastic material and/or for shaping a core of mouldable material.
