Abstract: This invention comprises apparatus and methods for folding and crimping shredded strips of sheet material into preselected lengths of interlocking, decorative material and/or bulk packaging material. The apparatus generally includes an attachment for a commercial paper shredding device which shreds sheet material therein. The apparatus comprises a movable barrier against which the shredded strips of sheet material are impelled upon being expelled from cutting blades of the shredding device. The movable barrier causes the strips to become controllably jammed within a confined area between the barrier and the cutting blades. Further insertion of additional strips into the confined area causes the strips to become compacted, folded, and crimped against a remaining dam of jammed sheet material located within the confined area. This causes the strips to fold and press against themselves, and form lengths of thin sheet material having an accordion-shaped configuration.

Abstract: Folded articles, such as paper napkins, handkerchiefs, and the like are puced of an intially continuous web or sheet material which is moved into a folding machine in a feed advance direction at a controllable feed-in speed. The sheet material may be folded once lengthwise around the feed advance direction before it is cut by a cutter operating at equal time intervals. The cut sheet material sections are then accelerated and after the acceleration they are folded at least once crosswise around a direction perpendicularly to the feed advance direction, whereby the cut sections travel at a constant speed during the crosswise folding and subsequent stacking. The feed-in speed is kept constant as long as articles of a given size are being produced. When the article size is to be changed, the feed-in speed is accordingly changed.

Abstract: Apparatus for subdividing a stack into a number of piles of overlapping sheets has an elevator which can move a stack upwardly in stepwise fashion between a belt conveyor and a horizontally reciprocable carriage for a pusher and a blade-like horizontal separating element which extends beyond the pusher in a direction toward the conveyor. When a selected part of the stack extends above the level of the upper reach of the conveyor, the carriage is moved toward the conveyor so that the separating element penetrates between two sheets of the stack and the pusher thereupon transfers the pile above the separating element onto the conveyor. Two hold-down devices enter the gap which is formed in the stack as a result of penetration of the separating element to prevent the topmost sheet of the remaining portion of the stack from participating in the movement of the separating element toward the conveyor. The thickness of the rounded tip of the separating element is less than 0.9 millimeter.

Abstract: The invention relates to a multiple pot comprising individual pots interconnected by connector portions so as to be capable of being pulled out. The multiple pot is used to raise and transplant seedlings of plants. The invention also relates to a method of fabricating the pot. The pot is designed especially to promote growth of roots across the side walls of the individual pots after transplantation. Also, the resistance encountered when the multiple pot is unfolded is reduced. Further, the individual pots are uniform in size. These feature arise from the facts that the connector portions are formed by applying a waterproof paste discontinuously and that a water-soluble paste is not applied around the edges of the individual pots created when the multiple pot is unfolded. Hence, a coating of the paste is formed in none of these portions. The multiple pot is fabricated by continuously carrying out three steps.
