Benefits of technology
[0007] Currently, the manufacturing of threads twisted at several strands, as in a sewing thread or fishing line, consists of a process with several steps which makes the final cost of the thread more expensive.
[0019] As can be observed in the previously mentioned patents, the evolution of the manufacturers double twisting machines for these kinds of threads has been mostly directed at attempting to fit into their machine design a large number of spindles and gathering spools of greater dimensions. What none of the manufacturers has produced so far is a kind of double twisting machine that provides greater versatility and facilitates the process of twisting more than two types of thread and a larger number of twists per metre simultaneously.
Problems solved by technology
Over the past few years the market has had certain defects in the production process of twisted threads for industrial and technical use.

Embodiment Construction
[0020] In order to solve the problems derived from the current situation, the single-position double twisting frame with precision weave pickup has been created, offering a number of advantages, essentially originating in the total freedom and flexibility in parameter and activation selection in each one of the modules.
[0021] It facilitates simultaneously obtaining on several modules spools of different formats and dimensions, so that a different length of spool can be reached in each module.
[0022] The possibility to individually control the speed of the drive roller and the distributor of each module, depending on the width of the thread, spool filling will always be the most appropriate both in length and density of the thread crossing.
[0023] It guarantees that the maximum thread production capacity will be obtained in each module.
[0024] As a consequence of the above, the activation of both the spindle and gathering being independent, threads of different physical characteristics ...

Abstract
The invention relates to a double twisting twister machine with precision weave pickup, which is characterized in that the production modules are designed to work autonomously and independently and that it is especially designed with directly motorized spindles to work with threads having different diameters (titer) and both natural and synthetic materials wound in large size bobbins with precision weaving. The modules can work simultaneously at full capacity since all elements are independent.
Description
OBJECT OF THE INVENTION[0001] The object of the present invention is related to a double twisting frame, whose production module is designed to work autonomously and independently and especially conceived with spindles that are directly motorized for working with both natural and synthetic threads of different diameters (linear densities) and materials, and gathered on large format spools with precision weave pickup.[0002] Over the past few years the market has had certain defects in the production process of twisted threads for industrial and technical use.[0003] Manufacturers of continuous synthetic continuous Polyester, Nylon, Polypropylene and Aramidic fibre threads, as well as Rayon for industrial and technical use, are continuously increasing the weight of gathering spools that they are selling to their clients, as in the following examples:[0004] Polyester (PES) spools, until a few years ago, weighed a maximum of 10.5 kg, and weights of over 16 kg. are currently in use.[0005]...
