HELICALLY WINDING APPARATUS AND METHOD IN A PRODUCTION LINE FOR MANUFACTURING A NON-METALLIC ARMATURE

The present invention generally relates to manufacturing of a composite armature, more particularly, to apparatuses for helically winding of a winding roving about a rod when manufacturing a composite armature. There is provided is a helically winding apparatus allowing use of internally unwound roving bobbins instead of sheaves. The helically winding apparatus for a composite armature production line, the apparatus comprising: * - a disk-shaped creel (1) rotatable about its axis, wherein at least two drums (2) designed to have internally unwound direct roving bobbins mounted therein are mounted on a base of the disk-shaped creel, and each drum is configured to rotate about its axis and to unwind direct roving threads from a bobbin inner side, wherein each drum for placing bobbins of the direct roving is provided with a thread tensioner (3) placed thereon to provide twisting of the direct roving thread relative to its axis when the drum is rotated about its axis to form a twisted roving, wherein the helically winding apparatus further comprises: * - a cylindrical sleeve (4) positioned in a center of the disk-shaped creel and configured to pass a reinforcement rod through a center of the cylindrical sleeve, wherein the cylindrical sleeve has holes (5) for passing the twisted roving therethrough and helically winding of the twisted roving about the reinforcement rod when the disk-shaped creel is rotated about its axis. A technical effect provided by the claimed invention is an increased produceability of the helically winding apparatus, increased productivity, and a reduced rejection rate. La présente invention concerne de manière générale la fabrication d'une armature composite, plus particulièrement des appareils pour l'enroulement hélicoïdal d'une mèche d'enroulement autour d'une tige lors de la fabrication d'une armature composite. L'invention concerne un appareil d'enroulement hélicoïdal permettant l'utilisation de bobines de mèche déroulées en interne au lieu de réas. L'appareil d'enroulement hélicoïdal pour une chaîne de production d'armature composite comprend : * - un cantre en forme de disque (1) pouvant tourner autour de son axe, au moins deux tambours (2) conçus pour avoir des bobines de mèche directe déroulées en interne étant montés sur une base du cantre en forme de disque, et chaque tambour étant configuré pour tourner autour de son axe et pour dérouler des fils de mèche directe à partir d'un côté interne de bobine, chaque tambour pour le pla
