Method for applying sizing to warp yarns

A method of treating individual textile yarns being supplied from a warp beam which includes the steps of removing the warp yarn ends from the warp beam, subjecting said individual warp yarn ends to a sizing process and drying said warp ends prior to said warp yarns being subjected to a weaving process on a weaving loom, wherein said sizing process comprises:

• providing a sizing material for application to individual warp yarn ends coming from said warp beam;
• providing a pair of elongated rolls having a nip between which said warp yarn ends are passed;
• biasing said rolls against one another at said nip;
• applying said sizing material to the surface of one of said rolls;
• providing a predetermined metered amount of said sizing material on said one roll at said nip by removing excess sizing material from said one roll prior to reaching said nip and said warp yarn ends;
• and
• said predetermined amount of sizing material corresponding to the amount of sizing to be placed on said yarn ends individually generally without any excess;
• delivering said warp yarns coming from said warp beam to said nip of said rolls;
• pressing said predetermined amount of sizing material into said yarns from one side thereof for sizing said individual warp yarn ends without rollback of sizing material on said warp yarn ends,
• whereby said sizing remains substantially on the same side of said warp yarn ends that it was applied and the amount of energy required during subsequent drying of said warp yarn ends is reduced.
