Title (EN) SHEET DECELERATION APPARATUS AND METHOD
(FR) APPAREIL ET PROCÉDÉ DE RALENTISSEMENT DE FEUILLE
Abstract:
(EN) The present disclosure relates to sheet deceleration apparatus and methods for decelerating a sheet of material for use in a sheet stacking or other application. The deceleration apparatus includes a pair of rotatable rollers (26, 28), being rotatable about first and second axes, the rollers positioned on opposite sides of the travel path. At least one of the rollers is moveable relative to the other to nip the sheet between the rollers to reduce the travel speed of the sheet (15). A vacuum conveyor (60) is further provided along the travel path subsequent the pair of rollers to control delivery of the sheet to a stacking hopper(ll). A third rotatable roller(72), or similar apparatus, may be included in some embodiments, for pushing the sheet of material away from the vacuum conveyor at the appropriate time.
(FR) La présente invention se rapporte à un appareil de ralentissement de feuille et à des procédés de ralentissement d’une feuille de matériau à utiliser lors de l’empilement de feuilles ou autre application. L’appareil de ralentissement comprend deux rouleaux rotatifs (26, 28), pouvant tourner autour de premier et second axes, les rouleaux étant positionnés sur les côtés opposés du chemin de déplacement. Au moins un des rouleaux peut se déplacer par rapport à l’autre pour pincer la feuille entre les rouleaux afin de réduire la vitesse de déplacement de la feuille (15). Un transporteur sous vide (60) est en outre disposé le long du chemin de déplacement après les deux rouleaux pour commander la distribution de la feuille dans un bac d’empilement (11). Un troisième rouleau rotatif (72), ou appareil similaire, peut être compris dans certains modes de réalisation, pour pousser la feuille de matériau loin du transporteur sous vide au moment approprié.
