Definitions

• the present invention relates to a device for ensuring the stretching and winding of thermoplastic son, in particular glass.
• the windings are in the form of coils, or more precisely still in the form of "cakes", these cakes being intended more particularly for applications relating to reinforcement.
• the cake-making is carried out using winders, which, as their name suggests, are responsible for winding the glass strands at very high speed (approximately 10 to 50 meters per second) which have been previously sized .
• winders ensure the drawing and winding of these filaments and the operating parameters of these winders condition with those of the die the dimensional characteristics of the wire, in particular the title expressed in tex (the tex being the weight in grams of 1000 meters fibers or yarns).
• the speed of the winding member of the winder is controlled so as to ensure a linear winding speed of the wire constant although its angular speed varies, this speed control being achieved by decreasing the speed of rotation of the spindle which supports the cake as a function of the increase in its diameter.
• Another important parameter which conditions the obtaining of a cake of optimum quality consists in its ability to be easily rolled out, without the presence of loops, parasitic knots, with limitation of friction.
• This aptitude for unwinding is determined by the nature of the construction law (which determines the magnification of the cake) which has been generated by the winder during the formation of the cake.
• This building law incorporates many parameters, one of the most important of which is the crossover ratio, often called RC and the thread title.
• the winders of the prior art generate a kinematics or a particular race for the thread from the combination of two movements: a first movement which prints a primary race for the thread and a second movement which prints a secondary stroke on the wire, the first and second movements are generally applied by a single organ with combined movement which is more generally known by the name of an embedding device.
• RC cross ratio
• These known winders essentially consist of a chassis generally positioned below a die, this chassis supporting the crisscrossing device and at least one spindle movable in rotation, this spindle being adapted on the one hand, to generate the cake and on the other hand, to support the latter.
• an embedding device comprises a member shaped as a helix, this helix movable in rotation about an axis makes it possible to position the wire on the spindle in rotation, the movement imparted by the propeller consisting essentially of a movement of oscillations or beats only over a portion of the length of the cake, this movement constituting the primary stroke.
• the propeller or any other equivalent device such as in particular a cursor movable linearly within a groove, can describe all or part of the length of the cake.
• the propeller is mounted movable in a relatively slow movement back and forth in translation on a shaft integral with the chassis and parallel to the axis of the spindle, this second translational movement imparting the stroke secondary to the wire and thus allowing it to cover all or part of the length of the cake.
• the wire moves from a substantially stationary point generally located in downstream of the die, in a cone whose opening substantially embraces the total length of the cake.
• dies comprising a large number of holes (typically several thousand).
• the use of these dies requires dividing the die into several plies of filaments and associating several plies (at least two) on the same spindle axis of a winder, so as to thus carry out the drawing and winding multiple cakes simultaneously.
