Abstract
The present invention relates to a method and an apparatus for the transverse gluing of veneer strips 1 to obtain a butt-glued veneer carpet 2. According to the invention a first sensor unit 4 and a second sensor unit 7 are provided for aligning a front edge and a rear edge 5, respectively, of a veneer strip 1 and the veneer carpet 2, respectively, by means of a plurality of transportation belts 8 to 11 and 12 to 17, respectively, in such a manner that said edge is exactly positioned within a center line of a heating zone 3.
Claims18
A method for transversely gluing veneer strips (1) to obtain a butt-glued veneer carpet (2), in which individual veneer strips (1) are supplied and aligned in their position relative to one another and to a heating zone (3) and are glued, characterized in that a veneer strip (1) is transported, that the passage of the edge (5) of the veneer strip (1) is determined by means of a first sensor unit (4), that in response to the values determined by the first sensor unit (4), the transportation path needed up to a desired position of the edge (5) of the veneer strip (1) in the area of the heating zone (3) is calculated, and that at least one transportation means is controlled on the basis of the values determined.
An apparatus for transversely gluing veneer strips (1) to obtain a butt-glued veneer carpet (2), comprising
- a first group of transportation means for supplying veneer strips (1),
- a first sensor unit (4) in the area of the first group of transportation means,
- a heating zone (3) arranged in a direction transverse to the direction of transportation (6),
- a second sensor unit (7) in the area of the heating zone (3),
- a second group of transportation means arranged downstream of the heating zone (3), and
- a control and/or adjustment unit.
The apparatus according to any one of clamis 14 or 15, characterized in that the optical sensors form vertical light barriers.
