A stuffer box crimping apparatus for thermoplastic filamentary tow which comprises a pair of a cylindrical parallel nipping rollers forming a nip therebetween, a stuffer box and a pair of cheek members arranged in contact with outer lateral side surface of the nipping rollers, and which is capable of continuously operating over a long period of time without replacement of the cheek members and is obtained by using high durability cheek members comprising a base layer made of a hard material and a soft surface layer consisting of a soft material and having a thickness of 0.2 mm or less, which soft surface layer is formed at least on a surface portion of the base layer to be brought into contact with the outer lateral side surfaces of the nipping rollers.

Stuffer box crimping apparatus

Method and system for transporting a filament-bundle from a spinning process to a successive drawing process in a factory of producing synthetic filament yarns. The filament bundle is transported by means of can-transportation system between two desired positions along a fixed carrying passage automatically. Full packaged cans filled with the filament bundle are transported along the fixed carrying passage by a carrying means from a receiving position below a delivery mechanism of a spinning equipment to a creeling passage adjacent to a creel of a drawing equipment, and empty cans are carried from the creeling passage to a reserving position along a fixed passage for the carrying means and thereafter carried to the above-mentioned receiving position one by one. The motion of the carrying means is controlled by a control means involving a control computer.
