Jogger for straightening sheets in tiers

Abstract

A jogger for straightening material in tiers. The material rests against at least two lateral baffles associated with adjacent sides of a stack-supporting surface. The stack-supporting surface can vibrate. A gantry travels back and forth in the same plane as the stack-supporting surface. The stack-supporting surface can be tilted out of the horizontal toward the two lateral baffles. A top-covering plate (21) is mounted in the gantry (16) and parallels the stack-supporting surface (3). The stack (40) is accommodated between the top-covering plate and the stack-supporting surface. Mechanisms (22) accommodated in the gantry lower the top-covering plate onto and raise it off the stack-supporting surface. Blowers (30 & 31) for forcing wind between the tiers are accommodated in at least one (25) of the lateral baffles (25, 26, & 27). At least one side-covering plate (33 or 34) closes off the space between the stack-supporting surface and the top-covering plate. The side-covering plate can be positioned at a right angle to the first lateral baffle by mechanisms for moving the covering plate toward and away from the parallel second lateral baffle. The stack is accordingly enclosed all around with the exception of an outlet for the wind.
