Abstract
A method of producing components (2) of wood or similar, whereby each component (2) is obtained from a panel (25) formed by fixing at least three parallel strips (15a, 15b) to a first sheet (5) of wood; inserting a honeycomb structure (20) inside each clear portion (18) defined on the first sheet (5) by the three strips (15a, 15b); and fixing a second sheet (24) of wood to the strips (15a, 15b); the panel (25) being cut along a longitudinal plane of symmetry of the strip (15a) located at an intermediate portion (13) of the first sheet (5), to form at least two components (2).
Description
- The present invention relates to a method of producing components of wood or similar.
- In wood component manufacturing, a machine is known comprising a conveying device for feeding along a given path a first sheet of wood or similar, which is substantially rectangular and bounded laterally by a peripheral edge comprising two substantially parallel longitudinal portions, and two substantially parallel transverse portions perpendicular to the longitudinal portions.
- The path extends through a first gluing station for attaching a first pair of strips of wood or similar along the longitudinal portions, and a second pair of strips of wood or similar along the transverse portions; a filling station for inserting a honeycomb structure inside the clear portion defined by the strips on the first sheet; and a second gluing station for attaching to the strips a second sheet of wood or similar, substantially identical to the first sheet, to complete the component.
- Known machines of the above type for producing components of wood or similar have several drawbacks, mainly due to the fairly poor flexibility of the machines, which must be set up each time according to the format of the components for manufacture.
- It is an object of the present invention to provide a method of producing components of wood or similar, designed to eliminate the aforementioned drawbacks.
- According to the present invention, there is provided a method of producing components of wood or similar, as claimed in the accompanying Claims.
- The present invention will be described with reference to the accompanying drawing, which shows a schematic view in perspective of a non-limiting embodiment.
- Number 1 in the accompanying drawing indicates as a whole a machine for producing components 2 of wood or similar, and comprising a known
conveying device 3 extending along a given path P and in a givendirection 4. -
Device 3 feeds along path P a substantially flat supportingsheet 5, which, in the example shown, is substantially rectangular and made of materials derived from wood, such as so-called MDF (Medium Density Foam) or HDF (High Density Foam) materials. -
Sheet 5 has a topmajor face 6 bounded laterally by a peripheral edge 7 comprising twolongitudinal portions 8 substantially parallel todirection 4, and twotransverse portions 9 parallel to each other and to adirection 10 crosswise todirection 4. -
Device 3feeds sheet 5 through afirst gluing station 11 having a number ofnozzles 12 aligned indirection 10 and for applying a given amount of glue firstly to the leadingportion 9 indirection 4, then toportions 8 and anintermediate portion 13 ofsheet 5 substantially parallel toportions 8, and finally to the trailingportion 9 indirection 4. - From
station 11,sheet 5 is fed through afirst feed station 14 where respective longitudinal strips 15 of wood or similar are glued toportions 8 andportion 13; which strips 15 are substantially parallelepiped-shaped with a substantially rectangular cross section, are parallel to one another and todirection 4, and, in the example shown, are of a length, measured parallel todirection 4, substantially equal to the length ofsheet 5, also measured parallel todirection 4. - In this connection, it should be pointed out that the strip 15 (hereinafter indicated 15a) glued to
portion 13 is substantially twice the width, measured parallel todirection 10, of each of the strips 15 (hereinafter indicated 15b) glued toportions 8. -
Sheet 5 andstrips second feed station 16 where respectivetransverse strips 17 of wood or similar are glued toportions 9 and betweenstrips strips 17 are substantially parallelepiped-shaped with a substantially rectangular cross section, and, together withstrips clear portions 18 ofsheet 5. - From
station 16,sheet 5 andstrips filling station 19 where a respectivehoneycomb filling structure 20, made, for example, of cardboard, is inserted inside eachclear portion 18. - At this point, the whole defined by
sheet 5, bystrips filling structure 20, is fed along path P through asecond gluing station 21 having a number ofnozzles 22 aligned indirection 10 and for applying glue to strips 15a, 15b, 17, and then through afinishing station 23 where a supportingsheet 24, of substantially the same shape, size and material assheet 5, is glued to strips 15a, 15b, 17 to complete apanel 25. - Finally, the newly formed
panel 25 is fed through acutting station 26 having acutting blade 27 forcutting panel 25 parallel todirection 4 and along a longitudinal plane of symmetry ofstrip 15a to form, in the example shown, two components 2 frompanel 25. - Obviously, in variations not shown:
- the number of
strips 15a is other than one; -
panel 25 is formed by gluingfurther strips 17 to intermediate portions ofsheet 5 and between adjacent strips 15, and is therefore also cut indirection 10 and along a longitudinal plane of symmetry of each ofstrips 17 glued to the intermediate portions ofsheet 5; - the shape of
sheet 5, and therefore of lateral edge 7, differs from that shown in the accompanying drawing; and - the shape, size, and arrangement of
strips 15 and 17 differ from those shown in the accompanying drawing.
