Title: Fan-fold paper stacking receptacle
Inventor: PASKVICH WILLIAM J
IPC: B65H45/101
Filed: 1997-10-20
Abstract: A container for stacking continuous web, fan-fold paper (4) and paper guide assembly (18) are disclosed. The container has a contoured bottom (40) that includes an extended center section (44) that is sloped, a toe section (46) at the lower end of the center section (44), and a crest (42) and fan-fold shelf (40) at the upper end of the center section (44) of the bottom (40) of the container. The center section (44) is sloped sufficiently to cause the sheets (6) of the continuous web (4) of printer paper to slide downward to the toe section (46) of the container and thereby become aligned with the stack (33) forming in the container. The toe (46) is aligned with the paper guide assembly (26) that is an abutment against which an edge of the paper stack (33) forms. The crease (33) in the bottom (40) of the container causes the paper to fold to reduce the tendency of the web (4) to bulge. The paper guide assembly (28, 32) guides the paper (4) as it falls from the printer chute (16) output into the container.

Abstract: The plough comprises a frame (4) connected to the transversal beam (3) of the draught-bar head (1), by means of a plough-beam (5) which constitutes one of the sides of the offsetting quadrilateral ABTE. The side AB which is common to the offsetting quadrilateral and the skewing quadrilateral ABCD, is made up of: an arm (22) integral with the frame (4) which extends from the axis B towards the axis A and, a lever (30) articulated between its two ends on an axis (31) arranged at the end of said arm (22), which lever is articulated on one side on axis A and on the other side on the offsetting cylinder (21), which cylinder is directly mounted on the plough-beam (5). The adjusting of the width by the action of the skewing cylinder (25) brings about a variation of the angle at the apex of the triangle formed by the axes A, (19) and (32) which results in the automatic correction of the offset X and gives it a value equal to the distance Z between two consecutive bodies.
