Abstract
Abstract A method of edge-wise joining strips of material such as veneer to form an elongated sheet, the method including feeding the strips one after another to assemble them edge-wise, providing pairs of threads, applying one of each pair alternately to the front and back of successive strips after the fashion of a weaving loom, and heating the threads to melt a thermoplastic adhesive and cause the threads to adhere to the strips.

Claims Analysis
Total Claims: 38
Claim 1
Independent Claim
230 words
A method of transversely assembling strips, such as veneers, to form larger sheets by means of a plurality of connecting threads adhered at right angles to the longitudinal extension of assembled strips, and comprising the step of: a. laterally introducing a first edgewise strip between thread guiding devices arranged adjacent one another, said strip being conveyed in a guide and disposed with its lower edge on a first abutment arranged displaceably, said abutment being secured for a holding operation above a downwardly extending path for the strip; b. retarding said first strip before it comes into contact by its front edge, viewed in the direction of travel, with a second abutment; c. displacing said first abutment so as to permit said first strip to move downwardly; d. after reaching its lateral end position, causing downward movement against the upper side edge of the preceding strip already connected to the sheet; e. during the descending movement of said first strip, effecting the following steps in a continuous fashion: 1. applying adhesive-coated threads to opposite surfaces of said first strip; 2. cementing said threads to said first strip by heat; and 3. weaving said threads above the upper longitudinal edge of said first strip so that the strip is secured in a wickerwork-like fashion; and f. returning said first abutment to a position in which it is ready to repeat step (a).
