CUTTING MECHANISM FOR A DUNNAGE CONVERSION MACHINE AND METHOD

A cutting mechanism is provided for a dunnage conversion machine 10 that selectively cuts dunnage sheet stock drawable through the cutting mechanism. The cutting mechanism includes a frame and a pair of opposed cutting blades through which the sheet stock is drawable. The cutting blades include a driven blade and a biased blade, each supported relative to the frame for movement into and out of contact with one another. The driven blade is movable towards the biased blade to cut the sheet stock. The biased blade is biased against movement away from the driven blade to allow for self-adjustability to counter wear of one or both of the opposed blades. Contact of the opposed blades with one another causes the biased blade to be deflected away from the driven blade. 1. A cutting mechanism for a dunnage conversion machine that selectively cuts dunnage sheet stock drawable through the cutting mechanism , the cutting mechanism comprising:a frame;a driven blade supported relative to the frame for movement towards a biased blade and across a sheet stock path along which the dunnage sheet stock is movable through the cutting mechanism, to cut the sheet stock into discrete lengths; andthe biased blade supported relative to the frame for pivoting movement towards and away from the driven blade, the biased blade being biased against movement away from the driven blade where contact of the driven blade with the biased blade effects pivoting movement of the biased blade against a biasing force in a direction of movement away from the driven blade.2. (canceled)3. The cutting mechanism of claim 1 , where the driven blade is linearly translatable towards the biased blade.4. The cutting mechanism of claim 1 , further including a blade guard coupled between the frame and the driven blade claim 1 , the blade guard configured to be commonly movable with the driven blade between an engaged position of the blade guard and a disengaged position of the blade guard claim 1 , and the blade ...

Apparatus and method for making a coil of dunnage

A dunnage conversion system for making a coil of dunnage from a sheet stock includes a coiler, a movable dancer upstream of the coiler and interposed in a path of the sheet stock, and a controller communicatively coupled to each of the coiler and the movable dancer. The coiler is configured to wind the sheet stock, and the controller is configured to control the speed of the coiler based on the position of the movable dancer to control tension of the sheet stock upstream of the coiler. The sheet stock drawn about the movable dancer may be a slit-sheet stock having a plurality of slits configured to expand under tension applied in a feed direction. The controller may be configured to control expansion of the slit-sheet stock upstream of the coiler allowing conversion of the sheet stock into a coil of relatively less dense dunnage prior to or during winding.

Forming assembly for a dunnage conversion machine, dunnage conversion machine and pre-prepared sheet stock material

A cushioning conversion machine converts a sheet stock material into a relatively lower-density cushioning dunnage product. An exemplary sheet stock material includes two sheets that each overlap a common side of another sheet and are connected to respective lateral edges of the other sheet. The conversion machine includes a forming assembly having a former for shaping and randomly crumpling the sheet material, a set of adjustable guide members to guide the crumpled sheet material to a feeding assembly downstream of the forming assembly, and a severing assembly downstream of the feeding assembly that separates discrete lengths of cushioning. The severing assembly includes a window frame passage that guides the crumpled sheet material to an outlet during operation of the feeding assembly and constrains the crumpled sheet stock material during operation of the severing assembly.

Aparato y método para fabricar una bobina de material de estiba

Un sistema de conversión de material de estiba (20) para fabricar una bobina de material de estiba (24) a partir de una lámina (22, 23) incluye una bobinadora (30), un bailarín móvil (32) aguas arriba de la bobinadora (30) e interpuesto en una trayectoria de la lámina, y un controlador (34) acoplado comunicativamente a cada uno de la bobinadora (30) y el bailarín móvil (32). La bobinadora está configurada para enrollar la lámina (22, 23), y el controlador está configurado para controlar la velocidad de la bobinadora (30) en función de la posición del bailarín móvil (32) para controlar la tensión de la lámina (22, 23) aguas arriba de la bobinadora. La lámina que se extiende alrededor del bailarín móvil (32) puede ser una lámina con ranuras que tiene una pluralidad de ranuras configuradas para expandirse bajo la tensión aplicada en una dirección de alimentación. El controlador (34) puede estar configurado para controlar la expansión del material en hojas cortadas aguas arriba de la bobinadora, lo que permite la conversión del material en hojas en una bobina (24) de material de estiba relativamente menos denso antes o durante el bobinado.
