APPARATUS AND METHOD FOR SUPPLYING A CONTINUOUS WEB OF CRIMPED SHEET MATERIAL

摘要

An apparatus for supplying a continuous web of crimped sheet material to a rod forming device comprises:—a winding unit (3) for unwinding the sheet material from a bobbin (21) on which the sheet material is provided,—a crimping unit (7) for crimping the sheet material,—a dispensing unit (8) for adding a particulate or liquid add-on material to the sheet material, and—a control unit (9) for controlling the various units of the apparatus in response to sensor signals received from the respective units. The dispensing unit (8) is arranged downstream of the crimping unit (7) when viewed in the direction of transport of the sheet material, and upstream of the rod forming device to which the crimped sheet material is supplied.

1. Apparatus for supplying a continuous web of crimped sheet material to a rod forming device, the apparatus comprising
a winding unit for unwinding the sheet material from a bobbin on which the sheet material is provided; a crimping unit for crimping the sheet material, a dispensing unit for adding a particulate or liquid add-on material to the sheet material; and a control unit for controlling the various units of the apparatus in response to sensor signals received from the respective units, wherein the dispensing unit is arranged downstream of the crimping unit when viewed in the direction of transport of the sheet material, and upstream of the rod forming device to which the crimped sheet material is supplied, wherein an amount of particulate or liquid add-on material to be dispensed by the dispensing unit is controlled for controlling a resistance to draw of a filter.
