摘要:
An inflatable cushion packaging machine including a housing, a driving mechanism disposed at a front side of the housing, a rolling shaft module disposed at a rear side of the housing, and a friction module is provided. A film roll is mounted to the rolling shaft module, wherein a free end of the film roll is engaged with and moved by the driving mechanism such that the film roll is dragged by the driving mechanism to rotate the rolling shaft module. The friction module assembled to the housing has a friction ring being coaxial with the rolling shaft module and a plurality friction rollers mounted to the friction ring. The friction ring is forced to lean the friction rollers against a side surface of the rolling shaft module and stop the rolling shaft module from rotating while the rolling shaft module not being dragged and rotated by the driving mechanism.

Die Erfindung betrifft eine Vorrichtung zum Erzeugen von Füllmaterial mit einer ersten Fördereinrichtung, welche zum Fördern eines langgestreckten Materialbands entlang einer vorgegebenen Förderrichtung geeignet und bestimmt ist, und mit einer ersten Schneideeinrichtung, welche dazu geeignet und bestimmt ist, das Materialband in einer von der von der Förderrichtung abweichenden Richtung in Streifen zu schneiden und mit einer Presseinrichtung, welche diese Streifen durch Matrizen presst, um so aus diesen Streifen das Füllmaterial zu erzeugen, wobei zumindest für die Presseinrichtung und die Transporteinrichtung unterschiedliche Antriebe vorgesehen sind.
摘要:
A dunnage conversion system (20) for expanding an unexpanded slit sheet stock material (23) to form an expanded dunnage product (26). The dunnage conversion system includes a converging chute (28) to inwardly gather laterally-extending edges of sheet stock material towards one another, causing random crumpling of the sheet stock material to form a modified ply. The conversion system also includes feed wheels (120) that advance the modified ply through the converging chute and pinch rollers (122) that cooperate with the feed wheels to expand the modified ply traveling between the feed wheels and the pinch rollers to form a dunnage product. The expanded dunnage product is expanded both in a longitudinal feed direction and in thickness as compared to the unexpanded slit sheet stock material, and thus is a three-dimensional product having increased volume and lower density per unit of length as compared to the unexpanded slit sheet stock material.

The invention relates to a device for the machine-production of a packing material product consisting of a single-ply or multi-ply continuous paper web, said device comprising a feed system for drawing the paper web into the device, thus defining a conveying direction, and a cutting device for detaching the packing material product from a run of three-dimensional packing material formed in the device from the paper web. According to the invention, a transport device adjoins the cutting device in the conveying direction, said transport device transporting the detached packing material product away from the cutting device.

A dunnage conversion machine includes a bunching assembly that randomly crumples at least two plies of sheet stock material into modified plies having a relatively thicker three-dimensional shape, and a feeding assembly that advances and connects together longitudinally-extending portions of the modified plies to form a dunnage strip. A diverter minimizes overlap of and encourages separation of lateral edges of the modified plies from one another, and a severing assembly severs distinct dunnage products from the strip. An exemplary resultant dunnage product includes two or more plies of crumpled sheet material interconnected along a longitudinally-extending portion having interconnected overlapped portions of each of the plies and a longitudinally-extending line of connection. Each ply may extend laterally outwardly along randomly crumpled edge portions having a crumpled lateral width greater than a lateral width of the longitudinally-extending portion, the edge portions extending from the line of connection to opposed, laterally-extending free edges.

A machine for converting a sheet stock material into a relatively less dense dunnage product includes both (a) a helical pre-form assembly having a cylindrical mandrel with a longitudinal axis and a guide member for guiding the sheet stock material from a supply thereof into a helical path along and around the mandrel so as to form a helical pre-form that rotates around the longitudinal axis and advances parallel to the longitudinal axis; and (b) a restriction in the path of the pre-form that slows the advance and rotation of the pre-form past the restriction, the restriction causing the pre-form to retard longitudinal advancement, to twist upon itself, and to permanently deform as it moves past the restriction, thereby longitudinally and helically crumpling the pre-form.
摘要:
A dunnage conversion machine (36) converts a sheet stock material into a dunnage product that is relatively thicker and less dense than the stock material, but is relatively thin and sufficiently flexible to function as a protective wrap. The conversion machine includes a feed mechanism (40) that advances a sheet stock material therethrough and a connecting mechanism (42) downstream of the feed mechanism. The connecting mechanism retards the passage of the sheet stock material therethrough by feeding the stock material therethrough at a slower rate than the feed mechanism feeds the stock material to the connecting mechanism. This causes the stock material to randomly crumple in a longitudinal space between the feed mechanism and the connecting mechanism.; The connecting mechanism connects multiple overlapping layers of sheet stock material together as they pass therethrough, including connecting at least one crumpled sheet to one side of one other sheet.
