Abstract
A method and a device for stretching a tobacco leaf or portions thereof, which is distinguished in that each tobacco leaf is deposited on an omnidirectionally elastic, substantially flat carrier, pressure is exerted on the leaf on the side remote from the carrier and subsequently adequate tensile force is exerted around the leaf in a plane of the carrier in order to stretch the leaf by friction with excessive tensile force without the risk of damage of the leaf, since only the friction between the leaf and the carrier is responsible for the stretching effect.
Claims9
A method of stretching a tobacco leaf or portions thereof characterized by the deposition of each tobacco leaf on an omnidirectionally elastic carrier, by exerting a pressure on the leaf on the side remote from the carrier and by subsequently applying adequate tensile stress around the leaf in the plane of the carrier in order to stretch the leaf omnidirectionally by an excessive extension of the carrier.
A device for stretching tobacco leaves which comprises a hollow cabinet having an opening defining a rim, an omnidirectionally elastic, permeable, skin-like leaf carrier disposed over said opening, means for subjecting the interior of said cabinet to vacuum so as to hold a tobacco leaf against said carrier, and means around said rim and engaging said carrier for omnidirectionally stretching said carrier thereby to smooth a tobacco leaf held against said carrier.
A method of stretching a tobacco leaf or portion thereof comprising the steps of:
- (a) providing an omnidirectionally elastic carrier;
- (b) depositing a tobacco leaf on said carrier;
- (c) holding said tobacco leaf on said carrier with a predetermined pressure such that predetermined frictional engagement is maintained between said tobacco leaf and said carrier and;
- (d) omnidirectionally stretching said carrier, while maintaining step (c), by an amount sufficient to stretch said tobacco leaf to an extended state.
