Fig. IA discloses a group of three gears (1) set in motion by an engine (2) both lodged in a chassis (3) such set of elements forming all together the cutting tool (4).

Preferably sustained by bearings, such gears are fitted with means (5) such as mandril (7) for fixing the tolls (6) which will act directly on the pieces of material suitable for the production of sponges such as polyurethane foam.

Fig. IB gives a perspective view of the cutting tool (4) described in Fig. IA the mandril (7) bearing already the cylindrical knifes (8) aimed for opening cylindrical cuts from the surface of the foam piece up to the desired inner point of the sponge.

Fig. 2A shows the position of the foam piece (9) over the working tray (10), both already attached in the frontal view of Fig.2B.

Working trays (10) e (10A), the last one shown as from Fig. 4A₃ are destined for the creation of a matrix for standard measures between the foam pieces (9) which ill be shaped as desired, acting those working trays (10) and (10A) as transportation vehicle of the foam pieces between the various production stages.

Fig. 3A shows the positioning of the cutting set (4) over a foam piece (9) which is already inserted in the working tray (10) to apply the vertical cuts which in the present example are cylindrical, however contemplating the possibility of any shape desired pending upon only on the cutting method used, among many other existing, some of which are better explained below.

Fig. 3B shows the raising of the working trays (10) e (10A) towards the cutting set (4) having inside a piece of foam (9) to permit the opening of the vertical cuts in the desired depth.

Fig. 3C is a perspective view from the foam piece (9) still sustained by the working tray (10) bearing already the cylindrical cuts inside which are located the foam portions (9A).

The sequence of Figs, from 4A to 4G shows how the portions of foam (9A) after being isolated from the rest of the foam piece (9) by the vertical cut but still linked to that foam piece (9) by the base, are extracted from the foam piece (9) by cutting their bases according to the production method of the present invention. Fig. 4A, shows the positioning of a foam piece (9) over the working tray (10A), incorporating now in its base a portion of material (10B) in shape, form and volume similar to the portions of foam (9A) aimed to get those portions (9A) pressed upwards and entirely exposed through windows (1 IA), as shown in Fig. 4B.

At Fig. 4B the foam piece (9) is shown already fixed over the working tray (10A), while it is resting over the foam piece (9) a mask (11) fitted with windows (HA) aimed to exert downward pressure over the foam piece against the working tray (10A) in order to expose through the windows (1 IA) the foam portions (9A) that should be removed, as demonstrated in Fig. 4C.

Once exposed but still linked to the foam piece (9) by the base the foam portions (9A) could be then removed by a simple cut applied, for example, by a cutting tool fitted with a flexible rotational blade (15), as shown in Fig. 4D.

After the removal of the foam portions (9A), the pressure exerted by the mask (11) is relaxed, as exhibit in Fig. 4E, forcing the reverse movement of the foam piece (9) to the original position before compression, as shown in Fig. 4F, revealing then the cavities (12) created due the removal of the foam portions (9A), as shown in Fig. 4G. Once the cavities (12) have been created inside the foam piece, however still incompatible in dimensions to lodge a regular bar soap, it is then applied the horizontal cut at the bottom of those cavities (12) by the cutting tool (4) of the Fig. 5 A, which is now fitted with cutting discs (8A) instead of cylindrical knifes (8), as revealed by the Fig. 5B.

First step of the process is the introduction of the cutting discs (8A) inside the cavities (12) up to its bottom, as demonstrated by Figs. 6A and 6B, and second by moving horizontally the working tray (10) inside which the foam piece (9) is inserted in all necessary direction to create a hollow (12A) adjacent to the cavities (12) compatible in dimensions to the bar soap that will be inserted, as indicated by Figs. 6C and 6D, being the final result of said horizontal cuts demonstrated in the frontal view of Fig. 6 E.

After concluded the step of creation the cavities (12), extraction of the foam portions (9A) and horizontal cut for opening the hollow (12A), the foam piece (9) is dully formatted to become sponge, as observed in Figs, from 7A to 7D.

Fig. 7A gives a view from the surface of the foam piece (9) where cavities (12) have been opened throughout the cutting line (12B).

At Fig. 7B are also present two hatched lines (13A) and (13B).

The lodging area (17) for the bar soap inside the sponge is delimited as demonstrated by Fig. 7B by the circle (12B) and by the hatched line (13A) which also represents the limits of the horizontal cuts applied inside the foam piece (9) by cutting discs (8A)

At Fig 7B is also identified the area delimited by hatched lines (13A) e (13B) that represents the amount of raw material not separated by the horizontal cut applied inside the foam pieces (9) by cutting discs (8A) and that will act as union element along the edges (16) while hatched line (13B) also represents the precise point where the cut for separation of sponges from the foam piece (9) should be applied.

Fig. 7C shows a model of cutting knife (14) for the Hydraulic Swing Arm Cutting

Machine type, for example, aimed for the cut and separation of the sponges from the foam piece

(9) through stroke, being the perimeter (14A) of the knives there existing precisely coincident to the perimeter where the final cut on the sponge ready for use will be applied which is represented by the hatched line (13B).

The application of cuts in the foam piece (9) of Fig. 7B by the cutting knife (14) causes the sponges to be separated from the foam piece (9) and individualized ready for use as shown in Figs. 18A e I 8B. In addition to the cylindrical format the cavities (12) for the passage of the bar soap towards the hollow (12A) those passage may acquire any alternative form such as rectangular, square, oval and many others by means of hot shapers fitted for example with electrodes or the like to get the shapers warmed in the proper temperature for cutting the piece of raw material.

Fig. 8A exhibits a cylindrical body (18) aimed to apply vertical and horizontal cuts, fitted with a rotational axel (18a) and an inner space (18b) for accommodation of the portion of foam resulted from the vertical cut applied in the piece of foam by the cylindrical body (18), and a channel (19a) for the reception and fixing through screws (19b) an element for cutting the foam which is represented in the present example by a flexible blade for vertical cut (21) destined to the round cut and further extraction of the material portion resulted from the vertical cut applied in the piece of foam cylindrical body (18) through which the cleaning element will be inserted within the sponge. Alternatively, such element for vertical cut could be represented by the simple sharpening of the inferior edge of the cylindrical body for inner cut (18) which makes contact with the piece of foam or just by the insertion in those edges of warming elements in adequate temperatures for the cutting of the foam The fixing of the flexible blade for vertical cut (21) in the lodge (19) at the cylindrical body (18) is shown in Fig. 8B, where is also illustrated the way of passage (20) of the axle (23) of the horizontal cut blade (22).

Fig. 9 exhibits the set formed by the horizontal cut blade (22) adjacent to the axel (23) which cause the round movement, as well as the driving wheel (24) aimed to transfer to the axel (23) the needed round movement.

At Fig. 8C the cylindrical body for inner cut (18) is seen, bearing already all the essential elements to perform its tasks of inner cut of the sponge, according to the objectives of the present Patent.

At Fig. 10 an exploded lateral view from the cylindrical body for inner cut (18) is given, aimed to demonstrate its functionality, where following characteristics are stressed: The passageway for the axel of the horizontal inner cut (20);

The set formed by blade (22) and axel (23), now set in movement by an engine (23A); The flexible blade for vertical cut (21) positioned at the end of the cylindrical body for vertical cut (22) aimed to avoid the contact between that blade and the structure of the foam piece until the flexible blade for vertical cut (21) has reach the desired depth for inner cut of the foam piece when the blade for horizontal cut (22) will be activated in horizontal circular movement provided by a source of power such as the engine (23A) for direct transmission of power to the axel of the horizontal cutting blade (21) as better explained by the Fig. 11 where it is seen that after the application of the circular anti-clock movement of the axel (23) the cutting horizontal blade (22) has moved to the same direction for cutting all portions of material located in the course of said movement.

On Fig. 12 the cylindrical body for external cut (25) also fitted with an rotational axel (25A), an inner space (25B) which diameter is equivalent to the external diameter of the sponge to be produced, a blade for vertical inner cut (25C) and optionally a gear (25D) for transmission of the rotational power to the horizontal blade through its axel (22).

The cylindrical body for external cut (25) could also be used as the last step in the process of producing sponges when a simple cut is applied in the cutting line (26A) as demonstrated in Fig. 13 A, to detach the sponge from the rest of the foam piece or even in combination with the cylindrical body for inner cut (18) in which case will be coupled to the cylindrical body for external cut (25) as demonstrated in Fig. 12A, acting these two cutting cylinders in association for, in one single operation, could be obtained the two inner and outer vertical cuts as well as the horizontal inner cut aimed for the creation of the lodging area for the bar soap. Fig. 13A discloses a foam piece (26) while Fig. 13B exhibits the same foam piece submitted already to the inner (26A) and outer (26B) vertical cuts.

Sequence of Figs, from 14A to 14F show the movements assumed by the set formed by the coupling of the cylindrical body for inner cut (18) to the cylindrical body for outer cut (25) for the execution of both the vertical inner (27A) and outer (27B) cut and the horizontal inner cut (34), better explained in Fig.l6F.

Already detached from the piece of foam by the vertical outer cut (27B), in Fig 14A could be seen a sponge (28) with a line of external cut (27A) made up by the cylindrical body (18) that also serves to define the desired diameter for the sponge to be produced. That same Fig.l4A also represents the beginning of the anti-clock movement indicated by the arrow (29) of the cylindrical body (18) for the application of the inner cut (26B) by the flexible blade (21) for vertical cut.

Simultaneously to the above described movement the progressive rotation of the axel (23) for moving the blade for horizontal cut (22) present in the body of the cylinder (18) in the direction indicated by the arrow (26B) in a complete rotation of 360° up to the return of that blade for horizontal cut (22) to its initial position, as better demonstrated in the sequence of Figs, from

14A to 14 F, resulting so not only in the horizontal cut (34), as shown in Fig. 16F, with diameter equivalent to the maximum length of that horizontal blade for horizontal cut (22), as delimited by the hatched line (30), and resulting also in the cut of the whole base that links the portion of material (3 IA) of Fig. 15, to be detached from the piece of foam (26)

The final stage of the cycle described by Figs, from 14A to 14 F which discloses the open space (31B) opened after the removal of the portion (31A) as well as the junction area (32) not affected by the horizontal cut (22) at the edge of the sponge that is represented by the hatched line

(30) indicative of the maximum cut limit of the horizontal knife (22) and the external cutting line (27A) made up by the cylindrical body for external cut (25).

At Fig. 15 a lateral view from the foam piece (26) is given after the application of the external vertical (27A) and internal (27B) cuts that result in the creation of portion of material (3 IA) to be detached from the foam piece (26).

Sequence of Figs, from 16A to 16F shows the steps taken for the application of the horizontal cuts (34) both for the extraction of portions of material (31A) to be detached from the foam piece (26) for the creation of an open space (31B), and for the creation of a lodging area (33) for the cleaning element to be use by costumers, such a bar soap.

At the sequence of Figs, from 17A to 17F an alterative method for creation of the cavity

(12) through the removal of portions of material (9A), as demonstrated by the Fig. 4G by which a central cavity in the desired dimensions is opened inside a foam piece by a rotational tool with vertical movement fitted with any abrasive material such as emery (38) sustained by an axel

(38A), creating so an adequate area for the introduction of cutting knives and cutting discs (8A), as exemplified in the sequence of Figs, from 6A to 6E, aimed for introduction and retention of the cleaning element such as a bar soap which will act in conjunction with the sponge so created.

The sequence of Figs, from 18 to 18C shows the application of hot element for getting the integral sponge. Fig. 18A discloses a tool for hot formation of the cavity (12) through which the cutting discs (8A) could be introduced for the creation of a hollow (12A) where the cleaning element is inserted and retained inside the sponge.

Sustained by the axel (36) through which the tool is rotated by the rotational engine, it can also be seen in Fig. 18A the chassis (35) fitted with separations (35A) between the positive electrical contact (35Bl) and negative electrical contact (35B2) aimed to receive electrical energy from outside and transfer it the hot cutting element (37) through the electrical positive contact points (37A) and electrical negative contact at the points (37B), aimed to warm the hot cutting element (37).

When the desired temperature is achieved, the hot cutting element (37) in positioned over the exact point where the cavity (12) must be created, moved downwards and turned 360° at that point.

Once rotated inside the piece of foam through the axel (36), the hot cutting element (37) will cause the portion of material contained inside the hot cutting element (37) to be vertically cut by the two sides (37C) of the hot cutting element (37), and at the bottom of that portion by the bottom (37D) of the hot cutting element (37), leaving so an empty space for the creation of the cavity (12).

Fig. 19A exhibits a sponge delimited by the cutting lines (27a) e (27b) before the removal of the portion of material (31A) for the creation of a open space (31B) gotten before the removal of the portion (31A) as shown in Fig. 19B which also exhibits the hatched line (30) indicative of the open space to be occupied by the desired cleaning element. Although the invention has been disclosed in a preferred embodiment many changes can be done without the abandon of the spirit and the scope of the original conception.
