Patent ES-381860-A1 (ES)
Title: Apparatus for the processing of wool fibres
IPC: D01G23/00
Filed: 1970-06-18
Abstract: Apparatus for the processing of textile fibers such as wool fibers to form a coherent and even layer of fibers at high velocity for further processing in which fibers are fed on a conveyor belt to a pinned cylinder, the pins of which have a negative inclination and which are forced by rotation of the cylinder into the layer of fibers picking it up from the conveyor and carrying it around. The fibers are then transferred to another pinned cylinder the pins of which also have a negative inclination and which rotates at a faster speed than the first pinned cylinder so that there is a drafting action between them, the fibers being completely stripped from the first pinned cylinder and transferred to the second either by means of a third pinned cylinder the pins of which pass between the pins of the other two or by means of a stripping plate partially encircling the first pinned cylinder to strip the fibers from its pins and lead then under a cover plate which partially surrounds the second pinned cylinder and which serves to hold the fibers while they are penetrated by the pins of the second cylinder. The fibers are finally stripped from the second pinned cylinder and passed to a second conveyor which conveys them for further processing. The negative inclination of the pins assists greatly in overcoming problems of stripping the fibers from the cylinders.

Patent ES-437271-A1 (ES)
Title: Crimped continuous filament yarn and method
IPC: D02G1/12
Filed: 1975-04-30
Abstract: A method and apparatus for texturing continuous filament yarn wherein the yarn is fed at a controlled rate and under controlled tension by a pair of feed rolls into a confined crimping zone against a mass of crimped yarn therein, causing the yarn to collapse longitudinally to form crimps which become part of such mass. Heat and pressure are applied to the yarn mass in the crimping zone to plastically deform the yarn and partially set the crimps. The crimped yarn mass is then fed at a controlled rate by means of toothed rolls from the crimping zone into a setting zone. Heat and pressure are applied to the yarn mass in the setting zone to fully set the crimps. The yarn mass is moved through the setting zone by an endless belt having upstanding teeth that positively engage the yarn mass. The pressure applied to the yarn mass in the setting zone is substantially sufficient only to keep the crimps closed during the final setting thereof. The crimped yarn mass is then fed from the setting zone into a cooling zone. The yarn mass is cooled in the cooling zone to a temperature below that at which the yarn undergoes any molecular structural alteration in the absence of the application of a substantial force thereto. Finally, the yarn is withdrawn at a controlled rate from the cooling zone in continuous filament form. One of the feed rolls is mounted on one end of a yoke, the other end of which has an eccentric mounting shaft, the movement of which allows the feed rolls to be perfectly aligned in skewness and parallelism. Proper alignment of the crimping and setting chamber with respect to the other elements is accomplished by providing the frame with a number of alignment shoulders against which the chamber is set upon installation.

Title: Air-cleaning system for textile machines
IPC: D04B35/32
Filed: 1979-04-06
Abstract: A tube (24) perforated with spaced nozzle openings (25) facing the yarn guide and loop-forming elements of a knitting machine, such as a circular knitting machine, or elements of a loom and supplied with compressed air so as to blow away dirt and lint that tends to collect at the sensitive locations, is mounted for movement back-and- forth and, also, up-and-down, and driven in reciprocating motion, so that relatively few nozzle openings serve for air cleaning for all of the loop-forming needles and the year guides without dead spots in which accumulation will form. For reducing the compressed air requirements, compressed air is only intermittently supplied. The reciprocating motion is likewise intermittent and the compressed air supply intervals occur only when the nozzle tube is in motion.
