Abstract

A spinning preparation machine has consolidating means for producing a roving from a fiber bundle and a drafting system for drafting the fiber bundle. The drafting system is arranged upstream of the consolidating means in a transport direction of the drafting system. A guide is arranged upstream of the drafting system for guiding the fiber bundle between a container providing the fiber bundle and the drafting system. The guide has a feed segment opposite from the drafting system and a delivery segment facing the drafting system. The spinning preparation machine has a winding device for winding the roving onto a tube, and a tube transport device for providing empty tubes and/or for removing tubes loaded with roving by the winding device. The tube transport device has a conveyor for transporting empty tubes and/or tubes loaded with roving, wherein the conveyors are arranged at least in part between the feed segment of the guide and the drafting system.

First claim

The invention claimed is:

1. A spinning preparation machine, comprising:
a consolidating means for producing a roving with a protective twist from a fiber bundle supplied to the consolidating means;
a drafting system upstream of the consolidating means in a transport direction of the fiber bundle to draft the fiber bundle;
a guide arranged longitudinally between the drafting system and a container that provides the fiber bundle to the drafting system, the guide comprising a feed segment opposite from the drafting system and a delivery segment;
a winding device disposed downstream of the consolidating means to wind the roving onto a tube;
a tube transport device disposed to provide empty tubes to the winding device or remove tubes loaded with roving from the winding device;
wherein the tube transport device comprises at least one conveyor to transport the empty tubes or remove the tubes loaded with roving, the conveyor operatively arranged at least in part between the feed segment of the guide and the drafting system;
a tube transfer device operatively disposed to transfer the empty tubes from the tube transport device to the winding device or the tubes loaded with roving from the winding device to the transport device; and
wherein one or both of the winding device or the tube transfer device are arranged at least in part between the feed segment of the guide and the consolidating means, or between the feed segment of the guide and the drafting system.

2. The spinning preparation machine according to claim 1 , wherein the consolidating means comprises an air spinning nozzle, wherein the roving is produced from the fiber bundle inside the air spinning nozzle by a swirled air flow.

3. The spinning preparation machine according to claim 2 , wherein the conveyor is disposed between the feed segment of the guide and one of: the delivery segment; the winding device; the tube transfer device; or the consolidating means.

4. The spinning preparation machine according to claim 2 , wherein the guide completely spans over and across the conveyor and tube transport device.

5. The spinning preparation machine according to claim 2 , wherein one or more of the following are arranged above the conveyor: the feed segment of the guide, the delivery segment of the guide, the consolidating means, or the tube transfer device.

6. The spinning preparation machine according to claim 2 , wherein one or both of the winding device or the tube transfer device are arranged at least in part below one or all of the guide, the drafting system, or the consolidating means.

7. The spinning preparation machine according to claim 1 , wherein the feed segment of the guide is spaced horizontally at least 50 cm from a feed roller of the drafting system.

8. The spinning preparation machine according to claim 2 , wherein, in a side view, the drafting system and one or more of the following are arranged along a common side of the consolidating means: the guide, the winding device, or the tube transfer device.

9. The spinning preparation machine according to claim 2 , wherein, in a front end view, one or more of the following are arranged behind the consolidating means: the winding device, the tube transfer device, the drafting system, the guide, or the conveyor.

10. The spinning preparation machine according to claim 2 , wherein, in a front end view, the feed segment of the guide is arranged behind one or more of the following: the drafting system, the delivery segment of the guide, the winding device, the tube transfer device, the conveyor, or the tube transport device.

11. A spinning preparation machine, comprising:
a consolidating means for producing a roving with a protective twist from a fiber bundle supplied to the consolidating means;
a drafting system upstream of the consolidating means in a transport direction of the fiber bundle to draft the fiber bundle;
a guide arranged longitudinally between the drafting system and a container that provides the fiber bundle to the drafting system, the guide comprising a feed segment opposite from the drafting system and a delivery segment;
a winding device disposed downstream of the consolidating means to wind the roving onto a tube;
a tube transport device disposed to provide empty tubes to the winding device or remove tubes loaded with roving from the winding device;
wherein the tube transport device comprises at least one conveyor to transport the empty tubes or remove the tubes loaded with roving, the conveyor operatively arranged at least in part between the feed segment of the guide and the drafting system;
a tube transfer device operatively disposed to transfer the empty tubes from the tube transport device to the winding device or the tubes loaded with roving from the winding device to the transport device; and
wherein one or more of the following are arranged above the conveyor: the feed segment of the guide, the delivery segment of the guide, the consolidating means, or the tube transfer device.

12. A spinning preparation machine, comprising:
a consolidating means for producing a roving with a protective twist from a fiber bundle supplied to the consolidating means;
a drafting system upstream of the consolidating means in a transport direction of the fiber bundle to draft the fiber bundle;
a guide arranged longitudinally between the drafting system and a container that provides the fiber bundle to the drafting system, the guide comprising a feed segment opposite from the drafting system and a delivery segment;
a winding device disposed downstream of the consolidating means to wind the roving onto a tube;
a tube transport device disposed to provide empty tubes to the winding device or remove tubes loaded with roving from the winding device;
wherein the tube transport device comprises at least one conveyor to transport the empty tubes or remove the tubes loaded with roving, the conveyor operatively arranged at least in part between the feed segment of the guide and the drafting system;
a tube transfer device operatively disposed to transfer the empty tubes from the tube transport device to the winding device or the tubes loaded with roving from the winding device to the transport device; and
wherein one or both of the winding device or the tube transfer device are arranged at least in part below one or all of the guide, the drafting system, or the consolidating means.
