- the SPINNING PROCESS FOR METALLIC PACKAGES FORMING WITH PRE-FLAP FORMING AND SPINNING EQUIPMENT FOR METALLIC PACKAGES FORMING WITH PRE- FLAP FORMING proposed hereby, enables the can body's pre- expansion allowing forming of a pre-flap previously to its expansion, while the equipment for its accomplishment makes feasible the use of the different expansion processes existing in the market, as it is able to neutralize the irregular loss effect of the can body's height as a function of its expansion, which harmed the flap formation, which being designed in an irregular form, used to exceed the tolerance measures, which consequently, would impair the forming of the bottom and the lid, compromising their tightness and hermetics, to the point of creating leaks.
- the deep necking processes are already known in the production of cans, aiming to achieve an area whose section, taken in the can body's radial direction, has a diameter smaller than the can body's nominal diameter, generally comprised close to its ends; that is, close to the lid or the bottom, which consists of, starting from the can body's nominal diameter, decreasing one of its ends, and this necking is accomplished with the intent of saving raw material in the lid or in the bottom, and also to make their stacking easier, being accomplished by half plugs process (die-necking), for small reductions, or by means of forming rollers process (spin-flow) for large reductions; however, one of the major nuisances of the cans with necking which use low thickness foils, is the occurrence of pinholes in the necking area, close to the can body welding, which compromises considerably the cans assembly line efficiency, as well as the metallic package image.
- the height decrease in an irregular form occurs for several reasons, such as: difference of hardness points of the plate making up the can body and the area in which it receives the electric welding, considering that the plate is less hard in the middle than it is the ends, and depending on the area used to form the can body, it may have different hardness points, which related to the area influenced by the welding, may turn the can body's ends totally irregular after its expansion.
- difference of hardness points of the plate making up the can body and the area in which it receives the electric welding considering that the plate is less hard in the middle than it is the ends, and depending on the area used to form the can body, it may have different hardness points, which related to the area influenced by the welding, may turn the can body's ends totally irregular after its expansion.

- PREFERRED INVENTION FABRICATION Figures 1A-6A, 1C-5C and 1E-7E show the stages of the usual processes already known of the state of the technique, while the figures 1B-6B, 1D-6D and 1F-7F show usual processes which adopt the SPINN(NG PROCESS FOR METALLIC PACKAGES FORMING WITH PRE-FLAP FORMING AND SPINNING EQUIPMENT FOR METALLIC PACKAGES FORMING WITH PRE- FLAP FORMING proposed herein, where the savings achieved with the adoption of the process shown in figures 1B-6B can be evidenced, when compared to the process shown in figures 1A-6A in what concerns the utilization of the raw material, which is significant, if the absolute number of produced cans is assessed, considering that this savings is due to the dimensions of the can bodies or "pipes", which in the process shown in figures 1A-6A have a 73mm diameter, while in the process shown in figures 1B-6
- the process 1A-6A uses a specific machine to conform the flaps, while in process 1B-6B the flaps forming is made along with the pre- expansion and pre-flaps operation which locks the can, besides eliminating also the formation stage of the die-necking; that is, the neck forming in the can body's bottom end which is made in the third stage of the process 1A-6A (fig. 3A).
- the third stage is dedicated to the can expansion by the conventional mandrel expansion process, where its height is decreased to 80.8mm, its top end diameter goes from 68mm to 70mm and its bottom end diameter increases from 68mm to 73mm, the largest expanded area diameter reaches 78.5mm and the body center remains with the 68mm diameter (fig. 3C), considering that the can body's height decrease on both sides,
- pre-flap forming occurs in the third stage of process 1D- 6D, known as "pre-flap" by spinning, before the expansion, and the can body top end pre-expansion is made in that stage, whose io diameter moves from 68mm to 70mm, the bottom end diameter increases from 68mm to 73mm, and the center diameter remains at 68mm, and the can body height is decreased to 89mm, the bottom and top pre-flaps also being formed, which lock the can body, preventing an irregular expansion to occur with its height decrease i5 (fig. 3D).
- top and bottom flaps are formed in the fifth stage of process 1E-7E decreasing its height from 97mm to 95mm.
- the flap calibration occurs in the fifth stage of process 1F-7F
- the first station (7) is accountable for the invitation forming; that is, by the can body pre-expansion and the top and bottom flaps forming, which occur by means of piston sets (23) provided with specific tools(24) for that purpose.
- the internal part of the first station consists of a gear (8) located in its base, which transmits movement to a bottom round
- this station may have several piston sets (23), depending on the number of can bodies/hours that one wishes to produce.
- the can body's expansion proper occurs in the second spinning station (10), giving it the final form, which may vary
- this second station has the same basic operation as the first station (7), that is, consists of a gear (13) located in its base which transmits movement to a bottom round drum (37) which is mechanically coupled, by means of a connection column (38) to the top round drum (39) while he bottom round drum, the connection column and the top round drum turn around a central column (40) which remains stopped and fixed to the machine base (29), having two circular cams mechanically fastened to the central column (40), named top cam (41) and bottom cam (42) inside the bottom drum (37) and top drum (39); such round cams have specific shapes in their perimeters which enable follower rollers (43), connected by means of supports (44) to shafts (36) move in each other, causing them to come closer or become apart, as per the profile determined by the cams, while specific tools (12) are installed on those shafts (36) ends; the tools shall perform the final expansion, that is, the final spinning which may vary as a function of the used tools (12).
- pistons or shafts (36) may vary as a function of the desired can bodies' numbers/hour
- the basic operation of the second station (10) is practically identical to that of the first station (7), but this second station is provided with a can follower device, which is intended to receive the can body from the intermediate star (9) and remove it after its course through the second station (10), placing it on the output star(16).
- the utilization of the can follower device is essential, whose purpose is to assure a perfect stability of the cans, as to falls as well as the positioning accuracy during the spinning process, taking into account the difference between the can body's diameter at the input and the can body's diameter at the output of the second station (10).
- the can follower device is fixed at the central column (10) and connection column (38) of the second station (10), which is fastened and mechanically coupled by Its bore to the central column (40) which remains static and fixed to the machine base (29) during its route, while the top face of that cam (43) is provided with a specific groove (44); a follower roller (45) runs through the internal part of that groove thus describing a circular path around the central column (40) corresponding to the cam groove (44) during the machine run, and this follower roller (45) is coupled to a shaft (46), which is positioned in the radial direction of the cam; the moving of that roller in the cam groove circumference allows back and forth movements of the shaft in the radial direction of the cam, and shaft (46) is guided during its course through the hexagonal hole existing inside a round bushing (47) fastened to the coupling column (38) having a half-moon shaped part (48) fixed at the outer end of the shaft which is intended to catch the can body; the geometry of the internal part of this half-m
- the quantity of that can follower device is in the same ratio as the piston systems (36) which comprise the station (10) and which by its turn, may vary as a function of the wanted quantity of can bodies/hour, which shall be previously set upon the machine construction.
- this can follower device is that it is able to operate in any can conveyor system, not being restricted to the can expansion processes.
- this device may be operated in any can conveyor system or machines/equipment for manufacturing cans, both in the horizontal and in the vertical position; besides, it may be used in the steel cans manufacturing processes, as well as in aluminum cans.
