Abstract (en)
[origin: ES8506430A1] For the production of crimped fibre pieces from reconstituted tobacco a mixture of tobacco dust and/or tobacco waste, binders and possibly additives is extruded by a special die or nozzle head to filiform intermediate products with preferably rectangular to slightly lenticular cross-section which immediately after leaving the die head can be cut to give crimped fibre pieces. For forming this crimping no further operation is necessary.
