Apparatus for depositing objects of small thickness, especially skins, e.g. for the stacking thereof

摘要

An apparatus for stacking skins uses an endless conveyor belt mounted on a support and driven by a drum at an upstream end, and passing around a pair of rollers. The latter are displaceable relative to the drum to define a pair of retractable and extendable conveyor arms at the downstream end by a pair of chains for cyclically displacing the rollers to extend an upper one of the arms while retracting a lower one of the arms simultaneously. A bar is affixed to the conveyor belt and is engageable with notches on the support upon the displacement of said conveyor belt for retaining a portion of the conveyor belt between the rollers.
