Embodiment Construction

[0043] The plywood combining machine 1 according to the first structure will be described schematically and in consideration of its functions below with reference to FIGS. 1 to 6 . For better illustration, the plywood assembly machine 1 is only partially shown here. The veneer assembly machine 1 comprises, in a known manner, a conveyor device with a lower conveyor chain 19 and an upper conveyor chain 21 . The lower transmission chain 19 is driven in the direction of the arrow ( FIG. 1 ) via the shaft 14 and the gears 20a, 20b. The upper transmission chain 21 is driven in the direction of the arrow ( FIG. 1 ) via the shaft 12 and the gears 22a, 22b. Between the two conveyor chains 19 , 21 at least two side-by-side veneer strips are conveyed in a known manner to a heating device (not shown) in order to join the two veneer strips to each other.

[0044] The plywood combination machine 1 also includes an input device 2, which is Figure 4 to Figure 6 shown in detail. The input...

Abstract

The invention relates to a device for drawing veneer strips (16) into a veneer assembling machine (1) and comprises a belt drive arranged between an insert area (15) for the veneer strips (16) and a conveying device (19,21) of said veneer assembling machine (1). A stop device (3) forms a stop for the inserted veneer strips (16). The stop device (3) is located at a distance from a vertex (R) in the direction of conveyance (X) of the belt drive. The stop device (3) comprises a first stop element (4), which is arranged above the belt (10), and a second stop element (7; 27) which is arranged to the side of the belt (10). The second stop element (7; 27) can be moved back and forth between a first position, wherein it is arranged above the belt (10) and provides the stop, and a second position, wherein it is arranged underneath the belt (10) and provides a through-passage between the first and second stop element (3).

Description

technical field [0001] The invention relates to a device for feeding veneer strips into a veneer assembly machine in which individual veneer strips are assembled together substantially longitudinally with respect to the fiber direction. Background technique [0002] Plywood combination machines are known in the prior art in different configurations. Such machines usually have a transport device consisting of upper and lower transport chains, by means of which the strips of veneer are guided through the heating zone and are pressed at their abutting edges in this case to Together. The veneer strips are provided with an adhesive on their abutting edges, which can be hardened by heating in the heating zone. The heat can cause a chemical reaction in the adhesive that hardens the adhesive and bonds the plywood strips to each other. [0003] Various methods for gluing wood panels are known in the prior art, among which butt gluing is very important. In the known machines used ...
