DESCRIPTION

"METHOD FOR MAKING ASSEMBLABLE COFFIN SHELL

SURFACES BY MOULDING AND COMPACTING WOOD PULP.

SURFACES MADE WITH THIS METHOD AND A SHELL ASSEMBLABLE WITH SUCH SURFACES"

The invention relates to "a method for making assemblable coffin shell surfaces by moulding and compacting wood pulp, surfaces made with this method and a shell assemblable with such surfaces». The entire shell of a coffin, which consists of two parts, i.e. the body and the lid, is formed by the surfaces of the body i.e. the bottom, the lateral surfaces, the struts and the legs, and the surfaces of the lid i.e the upper part (top) and the lateral surfaces. The method consists in that each of the aforementioned surfaces with which the shell of a coffin is assembled and formed, is made of wood pulp which is moulded into binary moulds, one part of which has a relief surface identical to the "negative relief of the external face of the corresponding surface and the other part of the binary mould, has a relief surface matching the "negative relief of the internal face of the corresponding surface. After moulding, wood pulp is compressed between the two mould parts to the desired thickness and until the compressed surface acquires the desired hardness, strength, stiffness, etc., then the two parts of the mould are separated removed and the so configured surface is removed ready for use. With this method are made all the shell surfaces which, with a little extra processing, are assembled and form the shell of the coffin.

Today, coffins are made of a wide variety of materials and designs, of wood or metal, such as wooden frames and wood veneer panels, or MDF, cellular compressed paper, etc. In all cases, the walls of the shell are formed by assembling special pieces with mainly flat or even convex surfaces which are firmly connected to each other by welding, nailing, etc. In such structures, various decorative elements or symbols are attached to the outer surfaces or additional special items for internal reinforcement in order to achieve the necessary strength and firmness of the shell.

In most cases, coffins are standardized, industrially manufactured ones, a small proportion of coffins being of special manufacture, handmade, with special carved decorations, etc. In these cases of mass production and industrial manufacture of coffins, the shells are formed by surfaces of almost identical dimensions and basic form and are mainly differentiated in the configuration of the external faces and the additional components attached thereto. In particular, in every shell consisting of two parts, namely the body and the lid, we distinguish: the body surfaces, namely the bottom, the front side (head), the back side (foot), the front right side, the rear right side, the front left side, the left rear side, the struts and the foot, and the lid surfaces, namely the upper side (top), the front side (head), the rear side (foot), the front right side, the rear right side, the front left side and the rear left side. For the manufacture of these surfaces, MDF slabs of standard sizes and commercial characteristics are commonly used as the main material, which are cut into the dimensions of each surface. The external face of these surfaces is suitably treated to take the desired form. The method and the basic works involved in surface treatment are almost identical for all cases and consist of the following: the MDF sheets are cut to the desirable width, usually 30 - 35 - 40 cm, to obtain the lateral surfaces. The one face of these pieces is machined (milling, grinding, etc.) and "carved" to form the desirable relief form. In cases where an external face with large curves is required and the thickness of the MDF slab is insufficient, configuration is made by fitting additional elements of wood or a thin MDF slab which is curved and fitted with special supports and glue. To the upper and lower parts of the lateral surfaces of the shell, specially shaped "cornices" are attached also made of MDF slabs cut into narrow strips. Each strip is machined into the desired form, by rounding the ends, carving, etc., and fixed to the lateral surface with glue and nailing. Sanding and puttying operations follow, done mainly by hand, repeated until the desired result is obtained and the surface is ready for painting. After configuring the external face, surfaces are cut to the exact dimensions of the lateral surfaces of the shell with the appropriate cut angles for optimal fitting of the joints. Similarly, the other surfaces of the shell are configured. On the external face of the lid (top), relief depictions, such as the Cross shape, are attached in the same way as the 'cornices'. The final outer surfaces of the shell are configured by suitable treatment, such as puttying of joints, grinding and colouring.

In addition to the above, there are limited cases of coffin manufacture by injecting mainly composite materials in special moulds of "closed type" for forming a single body or lid or individual surfaces and components in their final form. Efforts have also been made for forming a single lid and a single shell body with pressurized pulp to construct a coffin with surfaces without joints.

Some of the most important problems and disadvantages presented by the coffins made with the methods used so far are:

- They have a large labour cost, as many man-hours are required for both unskilled and specialized technical staff.

- They have an increased material-raw material cost, such as wood, MDF, and finishing materials, for forming the external surfaces and coating the joints. Puttying materials, primers, several layers of paint, etc., or alternatively specific special wood finishes (veneered surfaces) are required.

- The many and difficult joints of same or different materials require special technical and complex reinforcements in order to achieve the necessary strength of the shell.

- They are vulnerable to transport due to the many pieces and accessories used to make the shell, especially in constructions with relief and curved surfaces.

- For the manufacture of standard, industrially manufactured coffins, complex mechanical installations with a considerable number of skilled workers are required for mechanical works, which increases construction costs.

- By carving MDF surfaces to create relief designs and curved surfaces, thickness is reduced locally, resulting in a reduction of the surface stiffness and the occurrence of distortions causing problems in sealing (closing) the lid on the shell body. The texture of the surface is also "altered" and special smoothing and grinding operations are required with repeated layers of putty or other similar materials until the surface is ready for painting.

- In order to create the surface external face relief, MDF slabs are required to have a high thickness, resulting in an increase in the weight and cost of the material.

- Due to the machining process to configure the external face, the material wears away, also burdening the material cost.

The composition and characteristics of the MDF slabs are standardized according to commercial standardization. Thus, in conjunction with the relatively limited possibilities of machining the relief on the surfaces, the variety of forms and designs produced in mass production is limited.

- Constructing the two shell parts, i.e. the body and the lid, as a single surface without joints by moulding pressurized wood pulp, presents considerable technical difficulties and complexity in the manufacture and operation of complex moulds, with high manufacturing costs and corresponding difficulties in the stabilization process of the natural characteristics of the wood pulp, which are more pronounced when having low thickness shell surfaces. In addition, transport and storage of the shell in this form is very difficult and expensive and it is not easy to carry out part of its configuration elsewhere out of the unit and the production line.

The invention aims to remedy the aforementioned problems and disadvantages.

The " method for making assemblable coffin shell surfaces by moulding and compacting wood pulp" consists in that each of the surfaces of which a coffin shell is assembled and formed, is made of wood pulp which is moulded and compacted in binary moulds, of which one part is fixed and the other one movable. A suitable amount of wood pulp, is poured into the fixed part of the binary mould, which is fitted to a suitable housing (die) and has a relief surface of the same form and dimensions (width x length) with the "negative relief of the external face of the corresponding shell surface we want to manufacture. With the movable part of the binary mould, which is also attached to a corresponding die and has a relief surface of the same form and dimensions (width x length) with the "negative relief of the internal face of the corresponding surface, wood pulp is compressed to the desired thickness for a certain time, until the compressed surface obtains the desired hardness, strength, stiffness, etc. Then,, the movable part is removed and the shell surface is taken off of the fixed part, ready for use. Wood pulp is mainly produced by chipping and pulping wood by-products such as pruning branches or woodworking by-products, as well as from recyclable materials such as packaging materials, pallets, wooden furniture and wooden frames. The face texture (external and internal) of each surface is configured, according to the requirements, smooth or rough by choosing the proportional granulometric composition of the wood pulp. Fine chipping gives a smooth face texture. We can fabricate each surface with a different texture on the external and internal face if, in the fixed part of the mould, we first apply a quantity of fine wood pulp until a layer is formed to the desired thickness and then the remaining required amount is filled with coarse wood pulp. After compression we will have a surface with a rough internal face and a smooth external face ready for final polishing and painting, without any other treatment and with minimal finishing materials. By using coloured fine wood pulp, the external face of the surface is produced coloured, without needing additional materials and colouring operations. If before wood pulp moulding, a sheet of flexible and malleable material with the desired appearance (such as a sheet of paper with representations, colours, etc.) is attached to the fixed part of the mould and the whole relief surface, then the external face of the surface will be ready with the desired coating.

By suitably patterning the mould relief surfaces, externally curved ends ('cornices') and internally suitable "shoulders" for fitting respectively the lid (at the upper part) and the bottom (at the lower part) are formed at the upper and lower part of the lateral surfaces. Additionally, at the lower part of the internal face, vertical low height sockets are formed for fitting shell reinforcement struts. When the lateral surfaces have the same shape and same cross-section (height x width), the moulded surface has a length equal to or slightly larger than the total length of the individual surfaces, from which each of the lateral surfaces are cut to the final exact dimensions by bevelled edges. Alternatively, and particularly when a different cross-sectional shape or external face is required, the moulded surface is of the exact required length for each body side, that is, for the front side (head), for the back side (foot), for the front and rear right sides and for the front and rear left sides, with their ends bevelled at the appropriate slants for fitting their edges. The shell-forming assembled surfaces are stabilized by using a suitable adhesive (glue) at the points of contact such as the shoulders and the edges of the lateral surfaces. If required, depending on the size, shape and dimensions of the surfaces, their assembly at some locations is locally reinforced by means of nailing, metal forks, etc. To enhance fitting on the edges of the lateral surfaces, a wedge-shaped small depth groove is formed at each end at the upper part of each lateral surface of the body and at the lower part of each lateral surface of the lid. In each pair of opposed wedge grooves at the joints, a wedge-shaped link of respective cross-section and dimensions is embedded, whereby tightening and fitting enhancement of the two surfaces is achieved.

By manufacturing the coffin shell surfaces as described above, their configuration is such that they are assembled easily with very few machining operations and at a very low cost to form the coffin shell.

"Surfaces made with this method" for assembling the coffin shell are the body surfaces and the surfaces of the shell lid.

The surfaces of the shell body made with this method are as follows:

1. The bottom surface, which is flat with a thickness ranging from 10 mm to 20 mm, with six (6) or four (4) edges, with dimensions proportional to the desired shape and size of the shell. To enhance the rigidity of the surface and depending on the thickness and dimensions, longitudinal or transverse "reinforcements" are formed during moulding as elongated protrusions of greater thickness.

2. The surfaces for the body sides, which are six (6) or four (4) depending on the bottom edges, have a relief form on their external and internal face so that the thickness thereof is constant Irrespective of the form and shape of the external face. On the upper and lower part of the lateral surfaces, curved ends (cornices) are formed on the external face and suitable "shoulders" on the internal face for achieving lid fitting (at the upper part) and bottom fitting (at the lower part). At the lower part of the internal face, vertical low height sockets are formed to accommodate the reinforcement studs of the shell. At each end at the upper part of each lateral surface of the body there is a wedge-shaped, short depth groove, whenever fitting reinforcement is required.

3. The surfaces for the reinforcement studs of the shell body, which are plane with the same cross-section (thickness x height) and lengths depending on the shell dimensions. Their ends are configured to fit in sockets with a corresponding cross section at the lower part of the lateral surfaces.

4. Surfaces for the support legs of the shell, which are flat, with small dimensions and of a thickness from 2 to 4 cm, present an angular shape with an opening similar to that of the four extreme corners of the bottom surface and their outer edges are flat or curved.

The shell lid surfaces made by this method are as follows:

1. The upper part surface (top), which is flat or curved with a fixed thickness in the range of 10 to 20 mm, on the external face of which there are moulded relief depictions such as the shape of Cross.

2. The surfaces for the lid sides are six (6) or four (4) depending on the edges of the upper part. They have a relief form on their external and internal faces so that their thickness is constant regardless of the form and shape of the external face. On the upper and lower part thereof, curved ends (cornices) are externally formed with suitable "shoulders" internally for fitting the top (at the upper part) and the body (at the lower part). At each end of the lower part of each lateral surface of the lid there is a wedge-shaped small depth groove whenfitting reinforcement is required.

"A shell made of such surfaces" consists of two parts, the body and the lid. The body surfaces are: the bottom, the front side, the rear side, the front right side, the rear right side, the front left side, the left rear side, the reinforcement struts and the support legs. The lid surfaces are: the upper part (top), the front side, the rear side, the front right side, the rear right side, the front left side and the rear left side. By assembling the above surfaces, a coffin shell of any size may be made with the corresponding surface dimensions, in any shape or form, and with any configuration of relief and coloured representations on the external face.

The invention, while raising the aforementioned disadvantages, has the following advantages.

- Shell surfaces with fixed thickness cross sections may be manufactured without requiring additional machining operations to configure curvatures or relief designs or depictions on the external face, resulting in high strength and stiffness and avoiding distortion problems due to surface machining.

- Wood pulp produced from cheap raw materials such as crushed and pulverized wood by-products and derivatives, recyclable wood materials such as packing materials, pallets, old damaged furniture, etc. can be used, significantly reducing the manufacturing costs and contributing to protection of environment by recycling waste materials. - The entire production process is simple, with a standardized construction of the surfaces in an industrial production line of low cost manufacture and operation, with a small number of workers without special expertise, resulting in a further reduction in production costs while at the same time significantly improving the technical characteristics and quality.

- It is possible to manufacture without any limitations of technical treatment and costs, any form of external face, making it easy to produce surfaces with a wide variety of designs and reliefs.

- Assembly of the shell forming surfaces can be easily made in any assembly unit and in any place outside production unit thereof, resulting in high supply flexibility, reduced transportation and storage costs for materials and products, increased competition and as a consequence lowering of the sale price of finished products while at the same time enhancing small local societies through the diffusion and transfer of know- how.

- Pulpwood is prepared with specific materials selected for the specific use at a low cost and optimum "behaviour" for this use, so that manufacture of surfaces and the whole shell is achieved with exactly the required characteristics according to the applicable legislation, etiquette and consequently the optimum shell construction at a lower cost is achieved.

- It is possible to have different texture and a better external face on the same surface, formed with fine wood pulp in the first layer of moulding, resulting in material saving and optimal form of the external face (smooth ready for painting or already coloured) with significantly reduced material and finishing work costs.

- it is easy to apply "linings" on the external face at a minimal cost, with sheets of flexible material such as paper or other components, during the moulding process,

The "method for making assemblage coffin shell surfaces by moulding and compacting wood pulp, surfaces made with this method and a shell assemblage with such surfaces" as described above and illustrated in figures 1 to 12 refers to surfaces from which a coffin shell is assembled and manufactured, the latter consisting of two parts, the body (1 ) and the lid (2). The surfaces of the body (1) are: the bottom (1.1 ), the front side (1-2), the rear side (1.3), the front right side (1.4), the rear right side (1.5), the front left side (1.6), the rear left side (1.7), the reinforcement struts (1.8) and the support legs (1.9). The surfaces of the lid (2) are: the upper part (top) (2.1 ), the front side (2.2), the rear side (2.3), the front right side (2.4), the rear right side (2.5), the front left side (2.6) and the rear left side (2.7).

The " method for making assemblage coffin shell surfaces by moulding and compacting wood pulp" is characterized in that each of the above surfaces is made of wood pulp (5) which is moulded and compressed into binary moulds, one part of which is fixed (3) and the other a movable one (4). A suitable amount of wood pulp (5) is poured into the fixed part (3) of the binary mould (3.1 ), which is attached to a suitable housing (die) (3.2) and has a relief surface (3.3) presenting the "negative relief of the external face (7.8) of the corresponding surface (7) of the shell we want to manufacture. With the movable part (4) of the binary mould (4.1 ), which is also attached to a corresponding die (4.2) and has a relief surface (4.3) of the same shape and dimensions (width x length) with the "negative relief (7) of the corresponding surface (7), the mass of wood pulp (5) is compressed to the desired thickness and for a specific time until the compressed surface (6) has the desired hardness, strength, stiffness, etc. Then the movable part (4) is removed and the surface (7) of the shell is taken off the fixed part ready for use. To manufacture each surface (7), with different texture on the external face (7.8) against the internal one (7.9), an amount of finely powdered wood pulp (5.1) is first moulded in the fixed part (3) of the mould (3.1) until a layer of the desired thickness is created, adding in thereafter the other required amount of coarse wood pulp (5.2). After compression, we will have a surface (6) of two layers, the outer layer (6.1 ) with fine pulp (5.1) and the inner layer (6.2) with coarse wood pulp (5.2). The respective final surface (7) formed will have a smooth texture on the external face (7.8) and a rough texture on the internal face (7.9). Using a coloured fine wood pulp (5.1), the external face (7.8) of the surface (7) is already coloured. If, before moulding the wood pulp (5), a thin sheet of flexible and malleable material with the desired appearance (such as a sheet of paper with representations, paints, etc) is fitted to the fixed part of the mould (3.1) and to the whole relief surface (3.3), then the external face (7.8) of the surface (7) will be ready with the desired overlay.

By means of suitable configuration of the relief surfaces (3.3) and (4.3) in the moulds (3.1 ) and (4.1), curved ends (cornices) (7.1 ) externally and suitable recesses (shoulders) internally are formed on the upper and lower parts of the lateral surfaces (7) of the body (1 ) and the lid (2). On the lateral surfaces (7) of the body (1 ), shoulders (7.2) for fitting the bottom (1.1 ) and shoulders (7.3) for fitting the end (7.6) of the lid (2) are shaped. In addition, at the lower part of the internal face (7.9), low height vertical sockets-recesses (7-4) are formed to accommodate the reinforcement struts (1.8). Depending on the lateral surfaces (7) of the lid (2), a shoulder (7.5) is formed for fitting the upper part (top) (2.1) of the lid (2). When the lateral surfaces (7) are of an identical form and cross- section (height x width), the moulded surface (6) has a length equal to or slightly larger than the total length of the individual surfaces (7). From this surface, each of the lateral surfaces (7) is cut into the final exact dimensions with bevelled edges. Alternatively, and particularly when a different section form or external face is required, the moulded surface (6) has the exact length required for each side of the body (1) and the lid (2), i.e. for the front side (head) (1.2), (2.2), for the rear side (foot) (1.3), (2.3), for the front and rear right sides (1.4), (1.5), 2.4 and 2.5 and for the rear left sides (1.6), (1.7), (2.6), (2.7), with their ends (14) having the appropriate slants for their edges' fitting. Fitting of the shell-forming surfaces is stabilized by using a suitable adhesive (glue) at the contact points such as the shoulders (7.2), (7.5), the sockets (7.4) and the edges (14) of the lateral surfaces. If required, depending on the size, shape and dimensions of the surfaces (7), fitting is locally reinforced at specific locations with nails, metal forks, etc. To further reinforcing, a low depth wedge-shaped groove (7.7) is formed after moulding at the edges (14) of the lateral surfaces (7) at each end at the upper part of each lateral surface (7) of the body (1) and at the lower part of each lateral surface (7) of the lid (2). At each pair of opposed wedge-shaped grooves (7.7) in the joints, a wedge link (8) of corresponding cross-section and dimensions is embedded, whereby the two surfaces (7) are tightened and fitting thereof is reinforced.

"Surfaces made with this method" for assembling the coffer shell are the body surfaces (1 ) and the surfaces of the shell lid (2).

The shell body (1 ) surfaces made with this method are the following:

1. The bottom surface (1.1), which is flat, its dimensions depending on the shape and size of the shell. To reinforce stiffness, longitudinal or transverse "reinforcements" (12) are formed during moulding..

2. The lateral surfaces (7) for the front side ( .2), the rear side (1.3), the front right side (1.4), the rear right side (1.5), the front left side (1.6) and the rear left side (1.7). They have an relief form on the external face (7.8) and the internal face (7.9) so that their thickness is constant regardless of the form and shape of the external face. At the upper and lower part of the lateral surfaces (7), curved ends (cornices) (7.1) are configured at the external face (7.8) and suitable recesses (shoulders) (7.2) at the internal face (7.9) for fitting the end (10) of the bottom (1.1 ) and shoulders (7.3) for fitting the end (7.6) of the lid (2). Low height vertical sockets-recesses (7.4) are also formed at the lower part of the internal face (7.9) for the fitting of the reinforcement struts (1.8). When strengthening of the joint on the edges (14) is required, at each end at the upper part of each lateral surface (7) a low depth wedge-shaped groove (7.7) is formed

The surfaces of the shell lid (2) made with this method are as follows:

1. The surface of the upper part (top) (2.1 ), which is flat or curved, with a fixed thickness in the range of 10 to 20 mm, on the external face of which there are moulded reliefs such as the shape of Cross (14).

On the upper and lower parts of the lateral surfaces (7), at the external face (7.8), there are curved ends (cornices) (7.1) and on the internal face (7.9) there are suitable recesses (shoulders) (7.5) for fitting the end (9) of the upper part (top) (2.1). When strengthening of fitting at the edges (14) is required, a small depth wedge-shaped groove (7.7) is formed at each end at the lower part of each lateral surface (7).
