Abstract
An apparatus for producing bristle bundles has a shaft-like magazine for cut-to-length bristles and at least one tubular bundle gripper, which can be introduced into the magazine and separates a bristle bundle from the bristle supply and which is internally widened from the opening over a short axial length in a continuous curve and then has over most of its axial length an axially parallel wall, accompanied by the formation of a larger internal cross-section than the said opening. The magazine has a vibrating bottom, which "fluidizes" the bristles and vibrating wall portion pushing flush the said bristles.
Claims32
Apparatus for producing bristle bundles, the apparatus comprising:
- a shaft-like magazine for receiving a supply of cut-to-length parallel-positioned bristles;
- and
- at least one tubular bundle gripper having an opening with an internal cross-section corresponding to a desired cross-section of the bristle bundle, said bundle gripper being movable into the magazine so as to separate at least one bristle bundle from the bristles in the magazine, and
- wherein an interior of the bundle gripper widens from the opening in a constant curve portion over a short axial length portion, and, over a substantial remaining portion of an axial length a wall portion of the interior of the bundle gripper extends in parallel to a longitudinal center axis of the tubular bundle gripper such that the tubular bundle gripper has an internal cross-section greater than said opening.
Apparatus according to claim 14, wherein the at least one tubular bundle gripper is introducible into the magazine from one side and wherein the bristle bundle is moved by the piston to an opposite side of the magazine and into at least one guidance channel of a guide at the opposite side of the magazine.
Apparatus for producing bristle bundles, the apparatus comprising:
- a shaft-like magazine for receiving a supply of cut-to-length parallel-positioned bristles;
- and
- at least one tubular bundle gripper having an opening with an internal cross-section corresponding to a desired cross-section of the bristle bundle, said bundle gripper being movable into the magazine so as to separate at least one bristle bundle from the bristle supply, wherein the bundle gripper has an axially oriented external profile over a short length thereof in a vicinity of the opening, and wherein the external profile includes troughs arranged equidistantly along a circumference of the at least one tubular bundle gripper.
