Abstract
In un procedimento per manipolare strati di finitura nella composizione e nel trasporto di tavole di legno massiccio costituite da più strati, gli strati di finitura (1) vengono pressati, dopo l'uscita dalla macchina (4) che applica la colla fino al prelievo da parte del carrello di trasporto sotto vuoto (6), mentre rotolano sulla pista di rotolamento a dischi (2) e nella stazione di collocamento (22), dalla deposizione sul substrato fino alla sovrapposizione della lamiera di copertura (15), vengono mantenuti pressati in corrispondenza di svariati punti piano-parallelamente sul substrato. Nel dispositivo per l'attuazione del procedimento una seconda pista di rotolamento a dischi (5) è disposta sopra la prima (2) e può essere sollevata ed abbassata, in qualità di premi-strato rotolante per gli strati di finitura (1), negli spazi liberi (8) tra i carrelli di trasporto sotto vuoto (6), mentre nella stazione di collocamento (22) sono previsti due premi-strato a pressione lineare (14 e 18) che di per sé possono essere portati lateralmente negli spazi liberi (8) tra i carrelli di trasporto sotto vuoto (6) e qui possono essere sollevati ed abbassati.In a process for manipulating finishing layers in the composition and transport of solid wood boards made up of several layers, the finishing layers (1) are pressed, after exiting the machine (4) which applies the glue up to the removal from part of the vacuum transport trolley (6), while rolling on the disc rolling track (2) and in the placement station (22), from the deposition on the substrate to the overlapping of the cover plate (15), are kept pressed in correspondence of several points plane-parallel on the substrate. In the device for carrying out the method, a second disc rolling track (5) is arranged above the first (2) and can be raised and lowered, as a rolling press-layer for the finishing layers (1), in the free spaces (8) between the vacuum transport trolleys (6), while in the placement station (22) there are two linear pressure blankets (14 and 18) which in themselves can be brought laterally into the free spaces ( 8) between the vacuum transport trolleys (6) and here they can be raised and lowered.
