Apparatus and method for controlling fabric web
An apparatus for controlling a composite fabric having internal axial tows includes a support member configured to engage the fabric substantially up to a composite component form. The support member includes a nonslip portion directly engaging a first outer surface of the fabric. The apparatus further includes a primary securing member engaging and applying pressure on the fabric at a second outer surface of the fabric opposite the first outer surface. Upon displacement of the axial tows of the fabric relative to the first and second outer surfaces, the support member and the primary securing member substantially maintain original configurations of the first and second outer surfaces of the fabric engaged between the support member and the primary securing member.

METHOD AND INSTALLATION FOR PRODUCING A TWISTED SYNTHETIC YARN
A method and an installation for producing a twisted synthetic yarn, comprising a spin-drawing installation configured to produce continuous filaments from a liquid plastics material or granular material by at least one spinneret and then to produce at least one yarn from at least two continuous filaments. A downstream treatment apparatus treats the at least one yarn which is transferred, without interruption, from the treatment apparatus to a downstream twisting/cabling apparatus via a collection and transport apparatus in a continuous process from the spin-drawing installation to the twisting/cabling apparatus. The collection and transport apparatus is configured to compensate for a difference in a production speed between the spin-drawing installation and the twisting/cabling apparatus.
