Abstract
An apparatus for assembling warps of spun fibers and/or filament yarns present on yarn beams to form a warp present on a warp beam is described. This apparatus has a pneumatic pressure regulator (1), an electromagnetically operable pneumatic valve (2) downstream of the pressure regulator, a three-position rotary disk valve (3) downstream of the pneumatic valve, and pneumatically operable brake cylinders (4) of the yarn beam brakes (12) which are arranged downstream of the three-position rotary disk valve and connected in parallel with each other and a pneumatic by-pass limited in time so that asynchronous pneumatic braking of the yarn beams and of the warp beam during rapid braking is avoided. The by-pass serves to bridge the switching time of the three-position rotary disk valve (3). According to one embodiment, the control of the pneumatic valve (6) switchable with delay and of the pneumatic valves (7 and 8) occurs pneumatically. According to another embodiment, the control of the electric delay element (9) and of the pneumatic valves (10 and 11) occurs electrically.
