DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

The invention concerns a weaving machine having two mutually separable major assemblies of which one assembly contains at least means for removing a manufactured fabric and of which the other assembly contains at least a warp-beam support.


RELATED ART

A weaving machine of the above type is known for instance from the European patent document EP 0 565 958 A2 and offers substantial advantages as regards changing articles and/or warp-beams because such work need not be carded out directly at the weaving machine but for instance may be carried out remotely where more space is available.
It is further known to encapsulate a weaving machine wholly or in part using shielding means in order to establish a micro-climate in the vicinity of the machine. This microclimate may be improved further by local airconditioning and dust removal. Shields of acoustically insulating material are used furthermore to reduce noise pollution from the weaving machine. It is further known to fit the shields with drive means to automatically open these shields in case of yarn rupture so that the weaving operator can proceed unhampered when remedying the yarn rupture. However the known shields incur the substantial drawback that they present considerable impediments to changing warp beams and/or articles, in particular if it is necessary to exchange the weaving frames, the reed and the warp stop-motion, in addition to the warp beam.
The object of the invention is to so enclose a weaving machine of the above described type by shields that changing a warp beam and/or articles can be carried out very easily.


BRIEF DESCRIPTION OF THE INVENTION

This problem is solved by using an upper and/or a lower shield between the back rest and the fabric-removing means, the lower and/or the upper shield being composed of a set of covers each mounted on one of the major assemblies and complementing the lower and/or upper shield when the assemblies are joined to each other.
In this design the covers will not be obstructing when one of the separable assemblies together with the warp beam is being removed from the other assembly or is joined to it again. Furthermore the covers present no impediment during a change of warp beam and/or articles.
In a preferred embodiment of the invention the upper shield is composed of a set of covers each mounted to one of the major assemblies and complementing one another to form the upper shield when the said assemblies are joined together. As a result, when the two major assemblies are being separated, each will be amply cleared and thereby will be well accessible for cleaning.
Further features and advantages of the invention are elucidated in the following description of the embodiments shown in the drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

The weaving machine shown in FIGS. 1 and 2 comprises a first major assembly 1 and a second, separable major assembly 2. The second assembly 2 comprises two side frame parts linked by an omitted crosslink. The two side frame parts include the bearings 3 for a shaft 5 of a warp beam 4. Furthermore the side frame parts include affixation means 6 for a back rest 7 and a warp stop-motion 8.
The first major assembly 1 comprises means 9 to remove a fabric 12. In the shown embodiment, these means
