Abstract:
An apparatus for manufacturing a cushioning packaging material from a web-shaped material having at least two layers, the apparatus comprising a material supply shaft for deforming side edges of the web-shaped material into a substantially rolled shape with bead-shaped margins; and a device for receiving a deformed material and for joining layers of the deformed material along a substantially central region thereof in a direction of a longitudinal extent thereof, the device having at least one first wheel-shaped member and at least one second wheel-shaped member both having embossing sections provided at a periphery of respective wheel-shaped members and engaging each other for joining oppositely located edge regions of the supplied web-shaped material by embossing when rolled regions of the supplied web-shaped material pass between the embossing sections of the respective wheel-shaped members,wherein axes of rotation of the first and second wheel-shaped members lie in a plane that is inclined to a running plane of the deformed material, which is determined by a longitudinal extent of the supply shaft, and wherein the first wheel shaped member is formed as a chain wheel, and the second wheel-shaped member is provided with a plurality of pins on the periphery thereof, the plurality of teeth of the first wheel-shaped member and the plurality of pins of the second wheel-shaped member forming the embossing sections of the first and second wheel-shaped members, respectively.
