Document Type and Number:
Japanese Patent JPH06898
Kind Code:
A
Abstract:
PURPOSE: To execute normal folding in processing even a blank having large size in width and to make it easy to change size within a short time.
CONSTITUTION: Between two sets of folding units 11, there are formed an underside auxiliary belt conveyer 21 on which a blank center portion is mounted and an upper auxiliary belt conveyer 27 by which the blank center portion is pressed down. The underside auxiliary belt conveyer 21 can be moved upwards or downwards, therefore, it can be lowered for retraction in non-use time. The upper auxiliary belt conveyer 27 can move vertically and be regulated with respect to position and direction of flow, therefore, retraction becomes possible by upward movement and travel down in the stream direction.
