Abstract: A dunnage conversion machine (10) and method for providing strips of dunnage that better fill a void in a container are characterized by means (24) for separately guiding at least two sheets of stock material (14 and 16) to respective laterally-disposed regions of an inlet (20) to a conversion assembly (40) such that one sheet does not wrap around another sheet, and means (12) for converting the sheets into strips of dunnage that can readily separate and follow separate paths.

Abstract: An inclined position of a product, leaving a nip between two folding rollers of a longitudinal folding machine, is corrected. The product is pressed into the nip between the rollers by a folding blade that can be moved up and down relative to a folding table. The product thus leaves the nip between the rollers and is transported in a direction of transport. The time of passage of a leading or a trailing edge of a product is detected at two measurement points which are spaced apart from each other and which are arranged transversely to the direction of transport of the product to be folded. Based on the times of passage that are detected by the two measurement points, and on commutation and/or data processing techniques, a deviation between a time offset detected during the passage of the corresponding product edge at the two measurement points, and a nominal time offset, is determined and analyzed.

Abstract: The present invention relates to a machine for producing paper dunnage, which machine comprises a forming device (22, 22?, 22?) and a housing (2) which is penetrated by a guide channel (62). A drive (3, 54, 58) is provided in the housing, in order to convey a paper web (8) along a main transport direction through the forming device and the guide channel. The arrangement and/or the design of the guide channel after the paper web emerges from the forming device brings about a deflection in the main transport direction from a first direction (A) into a second direction (B).

The location of the small radius is fixed with a closed loop control system sensing the radius location and controlling the relative velocity of the two members. Strain in the web is adjusted with the size of the small radius, which is controlled by the adjustable gap and radius location.

Abstract: A folding machine includes a vacuum conveyor and a plurality of flip folders spaced along the length of the conveyor. A length of sheet material is fed downstream along the conveyor to position the lead end of the sheet in clamp members at a first flip folder. The end is clamped and rotated downstream and up above the remainder of the sheet which is continuously fed down the conveyor. The clamps are released to allow the lead end to fall over the trailing edge of the sheet, thereby completing a first fold which reduces the length of the sheet 50 percent. Successive lead ends of the sheet are folded by second and third flip folders to reduce the length of the sheet to 1/8 the length of the original sheet and increase the thickness of the sheet to eight plies. The final folded bundle is fed to a tuck folder which further reduces the length of the package 50 percent forming a folded package 1/16 the length of the original sheet and having 16 plies.

Abstract: Tractor drives of a high speed printer move a length of continuous-form paper longitudinally up from a box of fanfold stacked paper, through a print mechanism and downward for refolding onto a fanfold stack. A set of bead chains hang vertically from the printer frame on each respective side of the descending paper. The chains are positioned to interact with the folding paper. The chains swing against the paper to aid in creasing the paper at the folds in the proper fanfold direction. Each set of chains include an upper chain and a lower chain. The lower end of an upper chain hangs substantially above the lower end of a lower chain. The lower chain interacts with the folding paper at the beginning of stacking to aid in establishing the refolding stack and continues to interact to minimize jamming until the stack height exceeds a range for proper interaction with the lower chain.

Abstract: A table top buckle chute fold machine is disclosed in which improved and more reliable squaring of the paper to the folding rolls is accomplished by lightly driving an inserted sheet of paper with a friction roller against a selected one of several deflector assemblies. The deflector assemblies each include a deflector member spaced away from the rollers to direct the advancing edge of the paper inwardly so as to be abutted against the back of a recessed guide groove. An intermittently engaged drive roller causes the squared paper to be forcibly advanced against the groove, causing the sheet to buckle and be nipped between another pair of driven nip rollers, forming a first fold at the location determined by the location of the particular deflector assembly activated.

Abstract: A bale wrapping mechanism for wrapping a large round bale with a wrap material such as plastic sheet material or net, is mounted to the rear of a bale discharge gate. Drive rolls are located rearwardly of the gate and are selectively drivable for dispensing wrap material onto the rear end of a guide pan extending beneath and engaged with a portion of bale-forming belts extending between lower rear and lower front belt support rolls carried by the discharge gate. A guide finger assembly is secured to the front of the pan and includes a plurality of fingers located in gaps between the bale-forming belts and including forward end portions curved arcuately about the lower front belt support roll for directing wrap material about the roll and into a pinch point defined between the belts and a bale desired to be wrapped by the material.

Abstract: A draw tape for thermoplastic bags is made by feeding tape to a first pair of nip rolls rotating at a relatively slow speed and a second pair rotating at a fast speed. The tape is stretched to form thin and narrow central portions between end portions of unstretched tape. The first nip rolls are increased in speed, or are released to interrupt the stretching. When the rolls are closed, one of them is momentarily retarded or backed up, to produce a rapid transition in the tape between the unstretched end portion and the stretched central portion.

Abstract: A thermoplastic tape having thick and wide end portions with a relatively thin and narrow stretched central portion between them is produced by a first pair of nip rolls running at a slow speed, and a second pair of nip rolls running at a higher speed. The tape between the nip rolls is intermittently moved away from, and toward said first nip rolls to stretch it to produce the relatively thin and narrow central portion. The second pair of nip rolls is mounted on a pivoted arm so that they are movable toward, and away from said first nip rolls. Alternatively, an idler roll between the two pairs is moved toward, and away from, the first nip rolls.
