Title: Procede et appareil pour le transport de materiau solide
Inventor: JONKKA ARVO
IPC: B65G25/06
Filed: 2000-01-03
Abstract: L'invention concerne un procédé et un transporteur pour le transport d'un matériau solide au moyen d'éléments de transferts oblongs et parallèles (31, 32) qui se déplacent en va-et-vient dans le sens du transfert. Pratiquement toute la surface des éléments de transfert se déplace en même temps dans le sens du transfert et au moins une partie de la surface est inclinée vers le centre du transporteur. Les pièces (9) reposant sur les éléments de transfert les plus à l'extérieur (32) sont portées par le bord longitudinal de ces éléments de transfert, l'angle d'inclinaison dudit bord autour de l'axe longitudinal étant inférieur à l'angle d'inclinaison du bord supérieur. Ainsi, la force de soutien exercée par les éléments de transfert sur les pièces ou les parties reposant sur ces derniers et la force de friction entre eux et les pièces ou les parties reposant sur ces derniers, augmentent. En même temps, la force de soutien que les deuxièmes éléments de transfert inférieurs (1, 20, 31) exercent sur les pièces ou les parties reposant sur ceux-ci, et la friction entre eux et les pièces ou parties reposant sur ceux-ci, décroît.

Title: Low friction envelope feeder
Inventor: ANDREYKA JAMES B
IPC: B65H1/14
Filed: 2001-11-02
Abstract: An envelope hopper having a plurality of bottom rods to form a supporting surface for supporting a stack of envelopes and a paddle to push the envelopes towards an envelope feeder at the downstream end, A scrub wheel is rotatably mounted on a fixed, rotation axis on the paddle and is in contact with one of the bottom rods. The rotation axis of the scrub wheel is oriented at an angle relative to the rotation axis of the contacting rod, so that when the contacting rod rotates, it causes the scrub wheel to rotate, thereby producing a force on the paddle urging the paddle to move towards the downstream end. Preferably, the envelope hopper has a side rod on one side of the envelope stack, and the supporting surface is tilted from the horizontal surface, so that the envelopes are moved towards the side rod by gravity in order to register against the side rod. Preferably, the side rod also rotates in order to reduce the friction between the envelope stack and the side rod.
