Abstract
The invention relates to a sliver channel of a spinning plant preparation machine for the deposit of a fiber sliver in a container. The sliver channel is designed in form of a helix with changing gradient.
Claims6
A sliver channel for use with a sliver preparation machine for depositing fiber sliver into a container, said sliver channel comprising:
- an inlet having a substantially infinite gradient;
- a first portion immediately adjacent said inlet, said first portion describing a predetermined arc angle and having an increasingly flattening gradient from the infinite gradient of said inlet;
- a second portion immediately adjacent said first portion, said second portion comprising a helix having a constant gradient;
- and
- an outlet formed at the end of said second portion, said outlet being substantially parallel to a horizontal plane through said channel, said constant gradient of said second portion and said outlet forming a deposit angle with the horizontal plane within a predetermined range.

A sliver channel for use with a sliver preparation machine for depositing fiber sliver into a container, said sliver channel comprising:
- a substantially constant circular cross-sectional profile along substantially the entire length thereof;
- an inlet having a substantially infinite gradient;
- a first portion immediately adjacent said inlet, said first portion describing a predetermined arc angle of approximately 70 degrees and having an increasingly flattening gradient from the infinite gradient of said inlet;
- a second portion immediately adjacent said first portion, said second portion comprising a helix having a constant gradient;
- and
- an outlet formed at the end of said second portion, said outlet being substantially parallel to a horizontal plane through said channel and said inlet, said constant gradient of said second portion and said outlet forming a deposit angle with the horizontal plane within a range of approximately 10 to 20 degrees, said sliver channel defining substantially a semi-circle when viewed from the top thereof.
