Description

Process for the production of molded parts

The invention relates to a process for the production of molded parts, in particular for furniture or furniture parts, in which layers of sheet material, in particular paper, coated with glue, are laid one on top of the other, connected, shaped and cured.

Methods are known from DE 42 31 981 Cl and from DE 43 35 130 AI, in which paper webs are wound into a hollow roll after the glue application in order to produce molded parts. These windings can then either be pressed directly into a desired shape and cured or first compressed and cured in a press in order to soften the molded part again after intermediate storage and to press it into the final shape if necessary.

The finished molded parts are then used in particular as core bodies in upholstered furniture, where they replace the wooden core that was previously common in most cases.

On the one hand, these molded parts made of paper are cheaper to manufacture than the usual wooden cores and, on the other hand, they are also considerably lighter, which leads to a reduction in transport energy. In addition, these molded parts can be made from recycled material and are therefore particularly environmentally friendly.

ORIGINAL DOCUMENTS In order to achieve sufficient stability of the molded parts in this method, up to 15 laminate layers are sometimes required. In addition to the relatively long winding time per molded part, this also means a high paper requirement and the associated need for glue. The molded parts produced in this way are thus lighter than the usual wood cores, but still have a relatively high weight.

It is therefore an object of the invention to develop a method of the type mentioned in such a way that, with great stability of the molded parts, both the manufacturing time and the amounts of raw materials required are reduced and at the same time the weight is reduced, as well as molded parts produced thereafter and furniture formed therewith and . To disclose.

This object is achieved in that at least one at least partially expanded paper honeycomb part is laminated on at least one side, preferably on both sides, parallel to the honeycomb structure with at least one layer of sheet material as a honeycomb cover and is dimensionally stabilized.

The subclaims 29 and 41 relate to advantageous molded parts and finished parts produced by the method.

In the layer of sheet material, it can be, for. B. a layer of paper, cardboard or laminate but also a fiber or wood layer.

The molded part made from laminated paper honeycomb material using this process is very stable and resilient both in the direction of the honeycomb walls and the lamination, and is extremely light. It is still inexpensive to manufacture and requires less time than the production of molded parts using the winding process mentioned at the beginning.

It is particularly cheaper in the production of thicker molded parts with a thickness of more than approx. 20 mm than the production of molded parts made of solid plywood or the like. Subclaims 2 to 32 contain advantageous refinements and developments of the method according to the invention.

It is particularly cost-effective and advantageous if paper honeycomb material of a given thickness is first expanded to form semi-finished sheets and laminated at least on one side, preferably on both sides, with at least one layer of sheet material, and then blanks are produced from this semi-finished sheet and these blanks are further processed into the desired shape brought and stabilized form. The blanks from the finished plate semi-finished product can advantageously be made with conventional tools. This process therefore enables extremely fast and inexpensive production.

For the production of one-piece molded parts with a non-sheet-like outer shape, a paper honeycomb blank is preferably produced from initially folded paper material, and this is then optionally bent and / or kinked in the honeycomb material, the respective radius of curvature being essentially parallel to the honeycomb walls, to a given dimension expanded and then connected at least on one side, preferably on both sides, with at least one correspondingly cut layer of the selected flat material. The shrinkage that occurs perpendicular to the direction of expansion when the honeycomb material is pulled apart must of course be taken into account beforehand when cutting. In contrast O 97/16308 PC17EP95 / 04964

for the process in which initially manufactured semi-finished slabs are subsequently shaped, one-piece molded parts with any shapes are advantageously produced. So z. B. molded parts with polygons or round contours, such as. B. od a half cylinder as the upper edge of an armrest of an upholstered furniture. Like. Be produced.

It is also particularly advantageous if a plurality of molded parts are connected to one another to form an overall molded part. In this way, even more complicated molded parts can be built up from several parts. Furniture cores between approx. 20 mm and very voluminous parts of 200 mm and more can be created.

An essential aim of the invention is of course the creation of the end product according to the invention. The secondary claim 29 therefore contains a corresponding molded part, which was produced with the inventive method. Furthermore, claim 41 contains a piece of furniture or furniture part, which contains a corresponding molded part according to the invention.

The furniture produced with the molded parts according to the invention has an extremely favorable ecological balance. On the one hand, they are fully recyclable by simply separating the components. The molded parts according to the invention themselves can also be made from recycled material. As glue e.g. natural beech glue can be used.

In addition to upholstered furniture, the molded parts can also advantageously be processed into carcase furniture or containers, with curved walls, doors, floor and cover plates and inlays in particular being formed with them. The low weight allows one person to transport and load a take-away cabinet alone. Furthermore, the low weight brings advantages in the design of the swivel fittings of the doors and in particular in the sliding fittings of sliding doors.

In the manufacture of cabinet furniture, e.g. Paint the smooth, convex curved side of the cell layer material and in particular coat it with a water-based radiation-crosslinked starch plastic that is environmentally friendly. If increased fire resistance is required, this can advantageously be achieved by adding boron or silicate salts in the glue of the outermost lamination laminate layers or in a surface coating or impregnation. In addition to the glue, sodium or potassium silicate (water glass) develops a binding force when drying and curing.

Laminations with glass fiber fabric or the like are also provided if a special surface stability and tensile strength is required. Since these substances, which may not be degradable or can be recycled to paper, only affect the surface of the molded parts, they can be easily separated from the biodegradable materials for recycling at a later disposal.

The inner sides of the molded parts, which are provided with folds and / or overlaps on the concave bends, are then, if they are visible sides, either folded in an optically appealing manner or stepped or additionally laminated with a cover layer. Of course, this can also be done with the convex side.

In particular, they can be fitted with molded strips or mixed with wood veneer and upholstery. The superficial layer can be on the Fix the sticky paper base with glue without having to follow another compression step.

Half or three-quarter rounded edges can advantageously be formed at the edge regions, the honeycomb layers possibly also having to be placed on top of one another with a thin intermediate layer.

Full wraps of expanded honeycomb material can also be bent around a solid or hollow core and provided with an outer cover layer, which is preferably wound in multiple layers. In this way, high-quality columns and furniture feet can be produced, which have to be covered with a suitable surface material.

Fig. 18 as Fig. 17, only with elongated, rounded on the long side wooden core.

In the method according to the invention for producing molded parts (1 to 1f, 51, 55, 56, 60, 67, 70), at least partially expanded honeycomb parts (3) are coated on at least one side, preferably on both sides, with a layer parallel to the honeycomb structure ( 7) off sheet material, e.g. B. paper, wood cardboard, laminate, fiber material, laminated as a honeycomb cover and shape stabilized.

Depending on the desired final shape of the molded part, different process sequences are possible.

In the "pattern process", paper honeycomb material (4) of predetermined thickness is first expanded to form semi-finished sheets (2) and preferably laminated on both sides with a layer (7) of the selected material. Blanks (3z) are then produced from this semi-finished sheet (2) and these blanks (3z) are then brought into the desired shape and stabilized in shape by further processing (see FIGS. 1 to 4).

For easier deformation, the lamination layer (7) is preferably separated on one side at the desired deformation points of the semi-finished plate (2) or the blank (3z) or fold lines (5) are introduced into this lamination (7) for kinking or bending. The lamination can be cut in or the fold lines (5) can be pressed in either before or after the cutting process. The blank is then bent or folded in the direction of the incised or with a fold line (5) provided lamination side (7), so that the cut (6) or fold line (5) after bending or kinking on the concave side of the Cut (3z) in the longitudinal direction of the groove formed by the bend or kink.

For better stabilization in the kinked or bent position, the fold lines (5) can preferably be pressed in very strongly and the lamination (7) can be coated with glue in the crease area. When folded or bent, the ones lying on top of each other then stick Surface areas of the lamination (7) along the fold lines (5) on each other.

To produce relatively strong creases, the lamination (7) is preferably cut through on one side of the panel cut (3z) and on one side along the cut (6) up to a predetermined distance (6a) from the cut edge (6k) from the honeycomb material (4 ) and when the cut (3z) is bent, pushed over the lamination area (6b) on the other side along the cut (6) and, if necessary, connected to it in an overlapping manner to stabilize the kink or glued to it. It is particularly advantageous if the lamination (7) is not already glued to the honeycomb material (4) during the manufacture of the semi-finished plate (2) in the areas where such deformation of the semi-finished plate (2) is to take place during further processing. is connected, that is to say that the region is free of adhesive, so that after the lamination (7) has been cut open, the panel blank (3z) is kinked immediately and the lamination (7), as shown in FIG. 2, can be glued overlapping. There is no waste; the cell structure is compressed.

In order to achieve a particularly beautiful, smooth visible surface of bent panel blanks (3z), it is advantageous to cut the lamination obliquely on the inside several times in parallel in the bending area. When bending, the individual lamination sections at the intersections are then necessarily pushed one above the other due to the inclined cut and can be glued together in this position if necessary (see Fig. 8).

In order to stabilize the plate blank (3z) in the bent and / or kinked form, bending or Kinking the plate blank (3z) initially stretched to avoid later tension. Then the edge surfaces (31) of the blank (3z), which are essentially parallel to the honeycomb walls, with reinforced lamination (48) made of cardboard, laminate, plywood, hardboard, chipboard or metal or plastic or the like, or Combination of these materials, laminated, the honeycombs being covered along their longitudinal section, ie the two laminating surfaces (7) are connected to one another.

An additional stabilization is brought about in that a cover lamination (7d) is applied to the concave side in the bending or buckling areas. This is particularly advantageous because it allows a beautiful, smooth surface to be created even in the concave area.

For the rest, it is also advantageous for stability if the semi-finished plate (2) is already provided with differently textured laminations (7) on both sides during manufacture. It is important to ensure that the text direction on the side, which is the convex side after bending or kinking, is in the bending or kinking direction. On the concave side, the direction of texture should preferably be transverse to the direction of bending or kinking.

Furthermore, the semi-finished panels (3z) can also be connected to other molded parts (1 to lf, 51, 55, 56, 60, 67, 70) and / or furniture parts such as. B. slatted frames, seat cushions and the like. The respective furniture to be manufactured are dimensionally stabilized. For this purpose, recesses (32) for inserting and / or pressing in and / or gluing fastening parts (32b) are preferably made in the semi-finished plate (2) before the semi-finished plate (2) is formed. These fastening parts (32b) can be laminate or wooden pieces, hard foam parts, plastic parts, or the like. These can e.g. B. be provided with nuts or screw holes. Likewise, feet for setting up the finished furniture or the like can also be introduced into the recesses (32).

The lamination is preferably undercut when the recesses (32) are cut. The resulting edge protrusions (32r) of the lamination, which protrude beyond the recesses (32) in the paper honeycomb material (4), can then be bent inwards to form side walls (32w) in the recess (32). Larger adhesive surfaces are then available for gluing in the fastening parts (32b), so that increased strength is ensured (see FIG. 9).

For the optical covering of inserted fastening parts (32b) it is of course also possible to apply cover lamination (7d) to the molded part (1 to 1 f, 51, 55, 56, 60, 67, 70).

In another advantageous process sequence ("form lamination"), a paper honeycomb blank (4z) is produced from initially folded paper honeycomb material (4) and this is then optionally bent and / or kinked in the honeycomb material (4), the respective radius of curvature being essentially parallel to the Honeycomb walls lies, expanded to a given size and then preferably connected on both sides with a correspondingly cut paper, cardboard or laminate layer (7). With this method, the production of paper honeycomb parts (3) with almost any external contours is possible.

Recesses (32) for inserting and / or pressing in and / or gluing fastening parts are preferably made in the honeycomb material (4) before lamination. With this form lamination process too the paper honeycomb blank (4z) is preferably laminated on all sides. It is also advantageous here if the paper honeycomb blank (4z) on the edge surfaces (41) lying essentially parallel to the honeycomb walls has a stabilizing lamination (48) made of stiffer material, ie for example made of cardboard, laminate (48), plywood, plastic , Light metal or the like. Or from combinations of materials.

The edge surfaces (31, 41) of the paper honeycomb blank (3z, 4z) can be used both in the "cutting pattern process" and in the "mold lamination process" instead of simple reinforced edge lamination with solid molded edges (49), e.g. B. made of wood, plastic, laminate, metal or a combination of different materials. For this purpose, it is advantageous if the lamination (7) on the edges of the paper honeycomb material (4) projects above the paper honeycomb material (4), so that a gap is formed between the lamination (7) of the two sides. The mold edge (52) can then be glued into this gap (see FIG. 9).

A further possibility in the inventive methods listed here to increase the dimensional stability of the finished molded parts (1 to le) is to spray the honeycomb inner walls of the honeycomb material (4) at least partially with glue. The honeycomb inner walls then adhere to one another in the compressed zones of the honeycomb material (4).

The fastening parts made of laminate, wood, metal, plastic or the like can be inserted into the recesses (32), glued in or pressed in. Several of the molded parts (la to le, 55, 56) produced according to the invention can be connected to one another to form more complicated furniture cores to form an overall molded part (1). On the one hand, this can be done using the attached fastening parts. The individual molded parts (1 to le, 55, 56) can also be simply glued together. It is both possible to lay the molded parts (la to le, 55, 56) flat on top of one another and glue them. Butt butt joints are also possible.

When gluing the individual parts and / or layers together, preferably cold glue, eg. B. natural beech glue used.

Alternatively, provision can be made to connect the individual parts to one another at least selectively using hot glue. The deformation process then preferably takes place under the influence of heat. When they cool down, these glue points harden very quickly, so that the individual parts are temporarily kept in shape until the cold glue sets. Of course, the molded parts only get their full stability when the cold glue has hardened. By using hot glue, the production cycle can be slowed down.

During lamination, the glue can be applied to the lamination (7) as well as to the expanded or also to the non-expanded honeycomb material (4) by means of an application roller or spray system. In this case, application to the honeycomb material (4) is preferable for economic and ecological reasons, since the binders are minimized here. Hot glue can be applied, for example, by means of application guns as a bead or even over a large area both on the lamination (7) and on the honeycomb material (4). The finished molded parts (1 to lf, 51, 55, 56, 60, 67, 70) can preferably be coated with plastic or painted. An alternative possibility would be to provide the molded part surface with wood or plastic veneer (59).

In order to achieve fire resistance of the material, it is possible to add drilling or silicate salts to the glue or the lacquer or the finished molded part (1 to lf, 51, 55, 56, 60, 67, 70)) with an appropriate impregnation to provide.

It is also possible to carry out the lamination (7) or the top lamination (7d) with glass fiber fabric or the like. This also contributes to increased surface stability and is also flame retardant.

There are various options for cushioning the molded part (1 to lf, 51, 55, 56, 60, 67, 70). On the one hand, the entire molded part (1 to lf, 51, 55, 56, 60, 67, 70) can be foamed with cold foam. It is also possible to insert the molded part (1 to lf, 51, 55, 56, 60, 67, 70) into a cold foam molded part hollowed out on the inside or the molded part (1 to lf, 51, 55, 56, 60, 67, 70 ) into a cover (58) covered with foam (57) on the inside.

It is also also possible to previously NOZAG® springs, z. B. fixed with a textile tape to support the upholstery.

3 and 4, 6 and 7 and 11 to 18 show special embodiments of the molded parts according to the invention. Fig. 4 shows an armchair (1), which consists of a gem. Fig. 3 specially tailored molded part (la) consists of semi-finished plate (2), which is bent on one side around a round cut molded part (lb) serving as a seat and is attached to it.

6 shows a molded part (1) glued together from a plurality of individual molded parts (lc, ld, le) made from plate semifinished product (2). This molded part (1) serves as the core for an upholstered furniture side back acc. Fig. 7.

Fig. 11 shows a convex outwardly curved door (51), which consists of curved shaped plate semi-finished (2), in its concave side as upper and lower end and as an intermediate floor with correspondingly shaped frames (52, 53, 54) in the bending plane the semi-finished plate are arranged firmly connected. The frames (52, 53, 54) are glued to the semi-finished product (2). The longitudinal edges of the semi-finished sheet (2) are laminated with edges (48) made of a stiffer material and thus stabilized. In these edges (48) z. B. hinges. Like. Be attached. Such a component is of course not only suitable as a cabinet door, but also as a chest lid or as a specially designed cabinet wall.

In another interesting variant, decorative recesses (32a) are made in the semi-finished plate (2), B. produce a cassette door or wall (60)

(see Fig. 12). For this purpose, the lamination (7) and the paper honeycomb material (4) along the circumference of the recess

(32a) cut and the paper honeycomb material (4) pressed into the recess (32a) to a predetermined depth, so that a layer of compressed paper honeycomb material (4 *) is formed under the recess (32a). At the edge, this recess (32a) is covered with a decorative profile frame strip (32d), preferably all around the entire inner edge of the recess (32a). The profile frame strip (32d) is approximately Z-shaped and its free legs (61, 62) lie on the outer or lowered plate surface (63, 64). Of course, it is also possible to carry out this method inversely, so that thickened protruding cassettes are produced on a somewhat thinner plate. The cassettes can of course not only have a rectangular shape, but also round or other shaped polygonal edges.

According to an embodiment according to FIG. 13, the semi-finished plate (2) is bent through 180 ° in such a way that the honeycomb material (4) is arranged on both sides of at least one flat intermediate layer (65) and is connected to one another. The outside laminate layers (66) then form a final half-round. Such molded parts are suitable for. B. for armrests or backrest top edges. Likewise, it is of course also possible to turn over the semi-finished plate (2) at the edge by 270 °, so that the outer laminate layers form a round edge.

Further special embodiments are shown in FIGS. 17 and 18. In this case, expanded honeycomb material (4) with radially outwardly directed cell walls, which are laminated on the outside with laminate layers (69) and (72), are wrapped around a tube or a rod core (68, 71), in FIG. 11 this is a round timber. In principle, the core can have any shape. Such molded parts (67, 70) can, for. B. can be used as feet for furniture parts or as columns. The use of a stable wooden core has the advantage that very good fastening with other molded parts (1 to 1f, 55, 56) or pieces of furniture is possible. Fig. 14 shows a seating furniture body (55) which is bent from semi-finished products (2) in such a way that it runs continuously from an underside over a lower leg side, a seat surface, a backrest surface and a rear side to the underside. Stiffening plates (56), preferably also made from semi-finished plates (2), are arranged and fastened on the inside in the bending planes. The seam of the circumferential plate semi-finished product (2) is preferably located on the underside of the seat body (55).

FIG. 15 shows an enlarged section of the upper end of the backrest edge of the seating furniture body (55) from FIG. 14. The back of the seating furniture body (55) is laminated here with a veneer decor (59).
