Abstract From the Canadian patent

Abstract of the Disclosure, At hand looms a plurality of moveable parts of the loom are interconnected by means of so called tying up strings which, have hitherto been manually tied to the different loom parts. It is now proposed a system for a simplified and improved attachment of these tying up strings whereby the very tying up string consists of a crochetted string shaped as a continuous series of loops, which are used for effecting the interconnection of said loom parts either alone, in pairs and/or with or without, separate fitting members thereby eliminating the manual tying work.
