Abstract
A weft thread brake for shuttleless looms has a controllable braking effect. For this purpose, two rows of thread guide eyes are arranged in parallel to each other and between the thread supply reels or coils on the one hand and the thread presenting mechanism on the other hand. Brake leaf springs are arranged individually or in pairs for each weft thread, whereby these leaf springs reach approximately in the direction of the respective weft thread movement and into the space between the two parallel rows of thread guide eyes for cooperation with a common control rail which simultaneously presses all threads of a group of threads against the respective brake leaf spring. The braking action is individually adjustable for each weft thread by properly selecting the characteristics of the respective brake leaf spring or leaf springs.
