A machine for packing elongate bags for use with a waste disposal apparatus is disclosed herein. The machine comprises means for holding a reel of flexible tubing, the flexible tubing wound on the reel as a film having two parallel edges, the flexible tubing, when opened, forming a ring of elongate flexible tubing having an aperture at at least one end. The machine also comprises a pair of gripping means configured to engage and grip a region proximate to each edge of the film and draw the film of flexible tubing off of the reel, and a jig configured to be inserted into the aperture and hold a portion of the film in a ring around the jig, the jig configured to hold the film adjacent to and in engagement with the gripping means. Operation of the gripping means causes the film of elongate flexible tubing to be drawn over the jig and to be gathered in a ring of compacted flexible tubing around a base of the jig.

A folding machine for folding fiber products and fiber products formed and stacked thereby are disclosed. The folding machine includes two folding devices, each of which includes a cutting device, a delivery wheel, a folding-line wheel, a platen wheel, and a folding wheel. The cutting device cuts the fiber product and transports the cut fiber product to the delivery wheel. The folding-line wheel is adjacent to the delivery wheel for making a first folding line on the fiber product carried by the delivery wheel, and then the platen wheel folds the fiber product along the first folding line. Subsequently, the once-folded fiber product is transported to the folding wheel. The folding wheels of the two folding devices are adjacent to each other and are used to fold the fiber product passing therethrough for a second time, and thus fiber products with three folds are formed.

Disclosed herein is a sheet-folding apparatus which includes transporting rollers, folding rollers, a pushing member provided between the transporting rollers and the folding-rollers, and a guide unit for guiding the sheet to the folding-roller pair by using the pushing member.

The invention provides a fiber product suction system, comprising a folding wheel and a plurality of valves. The folding wheel comprises a plurality of protruding wheels and a plurality of recessing wheels adjacent each other. A plurality of suction channels and at least one connecting channel are disposed within the protruding wheel, wherein the connecting channel is fluidly connected to the suction channel. The valve is disposed on the recessing wheel of the folding wheel, and includes a connecting opening, a valve channel and a plurality of valve openings, wherein the valve openings are disposed on two sides of the valve, and are fluidly connected to the connecting opening via the valve channel. An air extractor can extract the gas in each suction channel through the valve, and generate a negative pressure on part of suction channels of the protruding wheel, so that the fiber product suction system can be used to suck and fold paper.

A method of manufacturing endless pallet chain sheet material is provided. The method includes: (a) providing a pallet having a longitudinal direction and a lateral direction perpendicular to the longitudinal direction; (b) providing a chain sheet material; (c) positioning the chain sheet material on the pallet to include a first row and a second row, wherein: the first row and the second row are arranged along the lateral direction; the first row is disposed at a layer the same as or below that disposed at by the second row; each of the first row and the second row includes N bundles arranged along the longitudinal direction, wherein N?2; and each of the N bundles includes an upper portion and a lower portion; and (d) connecting the lower portion of the first bundle of the first row with the upper portion of the N-th bundle of the second row.

A zigzag stacking device includes a stack table, swing roll, oppositely disposed positive and negative electrode unwinders, sealer, and controller. Positive and negative electrode plates and a separator are stacked on the stack table. The swing roll supplies the separator in a zigzag shape to the stack table by horizontal movement. The positive electrode unwinder supplies the positive electrode plate to a folded section of the separator folded in a zigzag shape. The negative electrode unwinder alternately supplies the negative electrode plate to a folded section adjacent to the folded section of the separator to which the positive electrode plate is supplied. The sealer presses and seals the separator when the separator is on the stack table. The controller controls operations of the stack table and sealer to seal the separator whenever the separator is stacked on the positive electrode plate and over the stack table.

Disclosed are embodiments of battery stacker machines, including z-fold stacker machines, configured to provide a rolling transfer of a battery layer so as to reduce scrubbing. In some embodiments, the layer is flexed onto an arcuate surface using a vacuum or other force. The arcuate surface is then rotated to release the layer at a desired transfer location. For instance, the desired transfer location may be on top of a stack or onto another arcuate gripper surface.
