Abstract: An energy-saving auto feed shredder which includes an operable cover as configured in a conventional auto feed shredder, with a pressing device configured on the cover. Once the cover is open, other components are exposed, such as a feeder base or compartment to place the stack of paper, a feeder slot in the middle of the feeder base or compartment, feeding mechanisms on both sides of the feeder slot, and a shredder mechanism below the feeder slot; when the cover is closed, the pressing device applies a pressure on the stack of paper inside the feeder base, and the feeding mechanisms in relative motion on both sides of the feeder slot captures and pulls the sheet at the bottom of the stack of paper under pressure, and force it to fold toward the feeder slot, and be delivered to the shredder mechanism. Repeatedly, new sheet of paper is captured, pulled, folded and delivered by the feeding mechanism, until the whole stack of paper is shredded.

Abstract: A lubrication package for lubrication of paper shredders wherein a lubricant is sandwiched between two coversheets which are sealed together near their peripheral edges to contain the lubricant. When the package is inserted into an operating paper shredder, the coversheets are shredded and release the lubricant to lubricate the shredding mechanism. The lubricant is prevented from all migrating towards one of the peripheral edges by a plurality of interior seals that divide the package into several sub-regions.

Abstract: A blade assembly for paper shredder consists of a first blade and a second blade combined back to back. Each blade has a circular blade flank formed by punching a thin sheet metal. The blade flank has a hole at its center and integrally extends outwards with at least two cutting edges. Each cutting edge has a base portion extended from the blade flank outwards and on the same plane as the blade flank, a surface portion bent from the base portion to the back of the blade flank and perpendicular to the blade flank, and a tip portion formed between the base portion and the surface portion. The blade flank is integrally formed with several ribs protruding towards the blade flank. A portion of the rib is formed beneath the tip to support the cutting edge and to enhance its strength.

Abstract: The present invention relates generally to the support system and waste receptacles for shredders. By removing certain supports in a shredder, the waste receptacle can be enlarged. In addition, openings in the shredder support walls allow the size of the waste receptacle to be increased, as well as facilitate disposal of other waste through the opening.

Abstract: The present invention relates generally to shredder openings or throats. Specifically, this invention teaches a shredder housing with a top throat to allow material to be disposed of from above the shredder, as well as a side throat to allow for material to be disposed of from the side of the shredder. This is accomplished by placing a guiding member in the throat to assist both the top and side input. In addition, two side throats substantially opposite each other allow for multiple users to simultaneously use the shredder. Finally, the guiding member can serve as a handle to assist in lifting the housing from the base.

Abstract: A lubricating pack specifically designed for paper shredders, including a piece of oiled paper saturated with lubricant placed between two jackets that are each provided at an inner layer thereof with an oil-seepage-proof film. The two jackets are then formed with a first seal sealed around their peripheries to form a lubricating pack having a laminating construction. The lubricating pack is fed into the paper shredder through a paper inlet to the paper shredder under auto mode to be shredded by the paper shredder. Accordingly, the cutting blades of the paper shredder would be able to contact the lubricant contained in the oiled paper during the process of shredding the lubricating pack, so as to provide lubrication between cutting blades of the paper shredder thereby extending the lifespan of the paper shredder.

Abstract: A swinging device for increasing the capacity of a trash bin includes a pushing assembly penetrating through the shredder body, a stirring board disposed at the bottom of the shredder body, and a shaft connecting the pushing assembly and the stirring board. The shaft converts the vertical displacement motion of the pushing assembly into a swinging motion of the stirring board. The shredded paper chips which typically form in a mound are thus pushed to the side and flattened. This helps reduce the space occupied by paper chips and increases the capacity of the trash bin, thus leading to less frequent emptying of the bin.

Abstract: This specification discloses the structure of a paper folding machine that can automatically fold paper documents such as bills, flyers, and letters. The structure has a first paper folding plate and a second paper folding plate disposed correspondingly, and a first roller set and a second roller set disposed between the first paper folding plate and the second paper folding plate. Paper entering the paper folding machine is driven by the first and second roller sets to the first paper folding plate and the second paper folding plate in sequence for paper folding. In particular, the paper folding style can be changed by adjusting the positions of stopping blocks on the first and second paper folding plates.

Abstract: The present invention relates generally to cutting blades for shredders. Specifically, this invention teaches cutting blades and a rotary cutting assembly which reduce the power needed to shred paper, plastic, and other forms of media that hold information. This is accomplished by creating a cutting blade with at least three adjacent teeth. The formation of three or more adjacent teeth more readily tears through paper and other media thus reducing the amount of power necessary to drive a shredder.

Abstract: The present invention relates generally to adaptable shredder housings which can be placed in or on top of various articles of furniture or waste baskets. Specifically, this invention discloses a shredder housing with at least one safety interlock switch which seamlessly fits into various articles of furniture or with multiple safety interlock switches which can fit over different sized bases or waste baskets.

Abstract: A device for reducing vibrations and noises of a paper shredder uses a buffer device comprised of a rubber cylinder and a spring between core fixing frames and the housing base of the paper shredder. The buffer device is fixed by using screw and washer, enhancing the vibration and noise reduction effect for the paper shredder.

Abstract: The present invention relates generally to cutting blades for shredders. Specifically, this invention teaches cutting blades, cutting blade assemblies, and a rotary cutting assembly which reduce the power needed to shred paper, plastic, and other forms of media that hold information. This is accomplished by creating a cutting blade with at least three adjacent teeth. The formation of three or more adjacent teeth more readily tears through paper and other media thus reducing the amount of power necessary to drive a shredder. This invention further discloses light weight cutting blades which require less material to manufacture, thus saving both materials and cost.

Abstract: A transporting conveyor for continuously laminating plural objects has a transporting belt and several resilient tabs disposed thereon in parallel. After objects to be laminated are disposed in lamination pouch films, they are held and positioned by the resilient tabs. The transporting belt slowly moves and sends the objects to be laminated and held on the resilient tabs into the laminator, reducing time required for laminating plural objects.
