Abstract
The invention relates to a method and to a device for producing highly compressed cylindrical bales from loose stalk material, such as hay or straw, which is picked up continuously and is compressed to form a rotating compressed roll which flows continuously in an axial direction. Individual compressed roll sections (bales) are successively cut off from the front end of the compressed roll. For producing dimensionally stable bales of varying length, the compressed roll, which is still subject to radial pressure, is bound automatically by a binder during its axially feeding and before a bale is cut off. The binder is delivered under tension and utilizes the rotation and feed of the compression roll.
Claims20
A method for producing highly compressed cylindrical bales from loose stalk material, comprising:
- picking up loose stalk material;
- forming a cylindrical roll by compressing and rotating the loose stalk material;
- feeding the rotating compressed roll in an axial direction thereof;
- binding at least a portion of the rotating compressed roll, while the roll is being axially fed and is subject to radial pressure;
- and
- cutting a bound portion of the roll to produce a dimensionally stable bale of a desired length.
A rolling principle baler for producing highly compressed cylindrical bales from loose stalk material, comprising:
- means for producing a compressed roll, said producing means defining a cylindrical rolling space therein;
- the rolling space being open at an end face thereof and adapted to be loaded in a circumferential direction;
- means for introducing loose stalk material into the rolling space;
- means for rotating the compressed roll;
- means for subjecting the compressed roll to radial pressure;
- means for feeding the rotating compressed roll along an axis of the rolling space;
- means for binding at least a portion of the rotating compressed roll, while the roll is being fed and is subject to radial pressure;
- and
- means for cutting a bound portion of the roll to produce a dimensionally stable bale of a desired length.
A cylindrical bale produced by a process comprising the steps of:
- picking up loose stalk material;
- forming a cylindrical roll by compressing and rotating the loose stalk material;
- feeding the rotating compressed roll in an axial direction thereof;
- binding at least a portion of the rotating compressed roll, while the roll is being axially fed and is subject to radial pressure;
- and
- cutting a bound portion of the roll to produce a highly compressed dimensionally stable bale of a desired length.
