A fabric which contains warp threads made of a delicate material is produced on a loom which includes a main reed and auxiliary end reeds at opposite ends of the main reed and which are independently operable with respect to the main reed. The warp threads made of delicate material are extended through the main reed and warp threads of a more robust material are extended through the auxiliary end reeds. As each filler (weft) thread is inserted in a shed the auxiliary end reeds are moved to beat the associated portions of the weft threads. Only after a plurality of weft threads have been inserted is the main reed moved to beat the associated portion of the weft threads, thereby reducing the frequency of movement between the dents of the main reed and the delicate warp threads and thereby reducing frictional destruction thereof.
A method of producing a fabric which has warp and weft threads, said warp threads being made of a delicate material and said weft threads being present in an amount of at least 20 weft threads per cm of warp threads, said method comprising the steps of
