Abstract
A device for spreading individual tobacco leaf halves, comprising a first conveyor formed by two endless elements, the operative runs of which are in contact with one another for clamping an edge part of the tobacco leaf portion and by a second conveyor, the conveying run of which joins the side of the first conveyor and the advancing direction of which is at an acute angle to that of the first conveyor, means being provided for lifting the operative runs of the first conveyor each time apart from one another, owing to the oblique conveyance of the second conveyor, the loose part of the tobacco leaf, laying on said second conveyor, which is moved away from the first conveyor while the transverse speed component of the second conveyor ensures stretching or spreading of the tobacco leaf.
Claims12
A device for stretching a tobacco leaf half comprising in combination:
- first conveyor means for moving a tobacco leaf half along a first path at a predetermined speed;
- second conveyor means for progressively intercepting, stretching and capturing said tobacco leaf half as it is moved by said first conveyor means and moving said tobacco leaf half along a second path divergent from said first path at a speed such that the direction of said second path has a component parallel and equal in speed to said first path and another component perpendicular to said first path whereby said tobacco leaf half is stretched in a direction perpendicular to said first path and captured in stretched state by said second conveyor means as it is moved along said second path.
A device for stretching a tobacco leaf comprising in combination:
- first conveyor means for receiving and moving two halves of a split tobacco leaf side-by-side along a first path at a predetermined speed;
- second conveyor means for progressively intercepting said tobacco leaf halves as they are moved by said first conveyor means and respectively moving each of said tobacco leaf halves along separate paths oppositely divergent from said first path each at a speed such that the direction of each of said paths has a component parallel and equal in speed to said first path and another component perpendicular to said first path whereby each of said tobacco leaf halves is stretched in a direction perpendicular to said first path and maintained in stretched state by said second conveyor means as it is moved along its respective divergent path.
A device for stretching a tobacco leaf comprising in combination:
- cutting means for cutting out the main rib of a tobacco leaf;
- first conveyor means for moving a tobacco leaf along a first path intersecting said cutting means and maintaining the severed leaf halves in side-by-side relation along said first path at a predetermined speed;
- second conveyor means for successively intercepting said leaf halves as they are moved by said first conveyor means and moving said leaf halves side-by-side along a second path similar in direction to said first path at a speed greater than said predetermined speed whereby each of said leaf halves is stretched in the direction of said paths and maintained in stretched state by said second conveyor means as it is moved along said second path;
- third conveyor means for progressively intercepting said leaf halves as they are moved by said second conveyor means and respectively moving each of said leaf halves along separate paths oppositely divergent from said second path each at a speed such that the direction of each of said paths has a component parallel and equal in speed to said second path and another component perpendicular to said first path whereby each of said leaf halves is stretched in a direction perpendicular to said second path and maintained in stretched state by said third conveyor means as it is moved along its respective divergent path.
A device for stretching a tobacco leaf half comprising in combination:
- first conveyor means for moving a tobacco leaf half along a first path at a predetermined speed;
- second conveyor means for successively intercepting said tobacco leaf half as it is moved by said first conveyor means and moving said tobacco leaf half along a second path similar in direction to said first path at a speed greater than said predetermined speed whereby said tobacco leaf half is stretched in the direction of said paths and maintained in stretched state by said second conveyor means as it is moved along said second path, said second conveyor means comprising a sequence of opposing clamping members carried by two endless elements travelling parallel to one another through a portion of their respective paths.
A device for stretching a tobacco leaf, comprising in combination:
- first conveyor means for holding a leaf lengthwise and transporting it along a predetermined path, at a predetermined speed;
- and
- second conveyor means for stretching and capturing the leaf as it is moved along said path whereby the leaf is transferred to said second conveyor means in stretched state.
