A yarn tensioner or brake for textile knitting machines having several tensioners on a support rod, each tensioner having a pair of tension cups which are pressed against each other by compressed springs supported from a stationary support. In a first embodiment, a stationary tension cup forms the stationary support and a floating tension cup alternates with respect to a stationary tension cup of an adjacent tensioner. The stationary tension cups have cylindrical protruding guides which slip fit into and guide the floating tension cups. In another embodiment, a stationary support supports compressed springs on both sides. The stationary support is formed of a circular support wall which has cylindrical protrusions on opposing sides and sized to slip fit into respective floating tension cups. A pair of stationary supports positioned on the support rod to support and guide opposing floating tension cups against each other. Each respective floating tension cup is driven by a respective coil spring. A first tension cup in each pair of tension cups that form a tensioner, has at least one nose guide that is positioned to be received by a receiving hole in a second tension cup. The nose guide is typically wedge shaped with an outer surface of the nose guide that is sloped inward to the center of the tensioner to force displacement of the floating tension cup as the yarn is pressed in between the first and second tension cups.
