Abstract

A machine for stacking and bundling flat articles. An upright stack of articles is formed on an elevator arm with the articles extending horizontally. A horizontal compressor foot is lowered to compress the stack. The stack is pushed into a generally Ushaped basket having open ends and parallel spaced sides. The basket is swung to a lay-over position in which the sides of the basket are upright to swing the stack to a position in which articles in the stack are upright. A basket clearing pusher assembly discharges the stack from the basket.

4. A machine as in claim 1 wherein the means for forming an upright stack of articles on the stack receiving arm includes means for measuring the height of the stack and means for lowering the presser foot when a stack of a predetermined height has been accumulated on the stack receiving arm.
5. A machine as in claim 1 wherein ends of the basket are open and there is a basket clearing pusher assembly and means for advancing the basket clearing pusher assembly crosswise of the basket at lay-over position to discharge the stack from the basket through one of the open ends in a direction lengthwise of the articles.
6. A machine for stacking and bundling flat articles which comprises a horizontal stack receiving arm, means for forming a compressible upright stack of articles on the stack receiving arm with the articles extending horizontally, a horizontal presser foot, means for lowering the presser foot over the stack to compress the stack, a generally U-shaped basket having parallel spaced sides and open ends, means for mounting the basket for swinging between an upright position in which the sides are horizontal and substantially aligned with the stack receiving arm and the presser foot in stack compressed position and a lay-over position in which the sides of the basket are upright, means for pushing the stack from between the presser foot and the stack receiving arm into the basket when the basket is in upright position, and means for swinging the basket to lay-over position when the stack has been received therein to turn the stack to a position in which the articles in the stack are upright, a basket clearing pusher assembly, means for advancing the basket clearing pusher assembly crosswise of the basket at lay-over position to discharge the stack from the basket through one of the open ends in a direction lengthwise of the articles, and track means on the sides of the basket, the basket clearing pusher assembly including a pusher member which passes through the basket as the basket clearing pusher assembly is advanced, the pusher member including guide means for riding on the track means to support the pusher membEr as the pusher member advances through the basket.
7. A machine as in claim 6 wherein there is second track means mounted on the machine and the guide means rides on the second track means when the basket clearing pusher assembly is in a retracted position clear of the basket.
