Measuring feeding device with brake shoe clamp

A yarn feeding device for a weaving machine, said device comprising:

• a storage body for storing a yarn storage unit defined by a plurality of yarn windings wound about said storage body in a predetermined winding direction by a winding element, said storage body having a yarn withdrawal area disposed adjacent the weaving machine from which yarn withdrawal area the yarn storage unit is withdrawn;
• a stop element disposed adjacent the withdrawal area of said storage body and an actuator which moves said stop element in a reciprocating manner between a stop position to block withdrawal of the yarn storage unit from said storage body and a release position to permit removal of yarn from the yarn storage unit on said storage body during repair of a fault condition;
• and
• a brake disposed downstream of said stop element in the winding direction and a drive which displaces said brake into a clamping position so as to act on at least the last winding of the yarn store disposed most closely adjacent the weaving machine, said drive displacing said brake into said clamping position at least as early as when said actuator moves said stop element into said release position such that when said stop element is released, the last winding relaxes only to the location of said brake and the yarn storage unit remains properly positioned on said storage body during repair of the fault condition.
