Abstract
A method and apparatus for opening fiber bales including a fiber removal element, compression means disposed upstream of said fiber removal element and advancing means near said compression means to advance the surface layer fiber material of a bale toward said fiber removal element.
Claims13
An apparatus for opening at least one fiber bale comprising
- a fiber removal element mounted for to and fro movement at a predetermined speed over a given plane to penetrate into a surface layer of a fiber bale in said plane for removal of fiber therefrom;
- at least one compression means disposed upstream of said fiber removal element relative to a direction of movement thereof for compressing the surface layer of a bale in said plane;
- and
- at least one advancing means near said compression means for extending into the surface layer of a bale in said plane with a given depth of penetration to advance the fiber material thereof towards said fiber removal element.

An apparatus for opening at least one fiber bale comprising
- a fiber removal element mounted for to and fro movement at a predetermined speed over a given plane to penetrate into a surface layer of a fiber bale in said plane for removal of fiber therefrom;
- a pair of rotatable guide rolls disposed upstream of said fiber removal element relative to a direction of movement thereof and extending at least over the length of said fiber removal element;
- and
- an endless conveying belt extending around said guide rolls for compressing the surface layer of a bale while moving the fiber material of said surface layer towards said fiber removal element.
1 more element
A method of opening a fiber bale comprising the steps of
- moving a fiber removal element at a predetermined speed to and fro over a surface of at least one fiber bale to remove fiber flocks therefrom;
- compressing the surface layer of the bale upstream of the fiber removal element relative to a direction of movement thereof;
- and
- additionally advancing the compressed surface layer of the bale toward the fiber removal element in opposition to said direction of movement.
