Abstract

A dynamic buffer suitable for supplying piles from a cutting station to a continuous stuffing system has two storage levels, upper and lower, each having parking cells arranged in series for receiving, retaining and dispensing the piles. Each cell comprises two consecutive roller-counter-roller pairs, spaced by a distance smaller than a longitudinal extension of the piles, motorized in synchrony, suitable for adheringly gripping and drawing a pile; a sensor designed to detect whether each parking cell is free or occupied by a pile. An electronic managing and command unit receives signals provided by the sensor and pilots the flow of piles in inlet to the storage levels, transfers the piles to successive cells and enables outlet of the piles from the storage level, the electronic unit acting in phase relation with the cutting station and the stuffing system, such that the supply of the piles thereto has a cadence proportional to the operating velocity thereof.
