Abstract
In a tufting machine for making patterned pile fabric, each thread passes on two successive guiding pulleys horizontally spaced from each other and selectively displaced vertically independently from each other by the hooks of a loom Jacquard. A thread-lowering beater bar is vertically reciprocated between these pulleys in unison with operation of the machine to draw from the supply bobbin a predetermined length of thread for the formation of a pile loop by the corresponding needle of the machine, a unidirectional thread clamping device being provided between the second pulley and the needle to prevent thread being drawn from the needle itself. The length of thread thus fed to the needle at each advancing stroke of the latter thus varies as one or both of the pulleys are raised by the Jacquard. A stationary bar may be disposed at an adjustable height laterally of the pulleys to permit of altering the length of thread fed to the needle when the adjacent pulley is low.
