FIELD: agriculture.SUBSTANCE: group of inventions relates to agricultural machinery industry and can be used to transport harvested agricultural crops. The seamless belt of canvas apron comprises an elongated flat structure of the base and a plurality of cross-bars. The flat structure of the base consists of fabric and rubber. The cross-bars comprise the structural core inserted into the rubber. The elongated structure of the base and the cross-bars are vulcanised and bonded together, except for the end sections to form a flexible elongated structure. The ends of the structure of the base are laid overlapping one another and vulcanised to form a seamless belt.EFFECT: use of the group of inventions provides creation of canvas apron belt with increased flexibility and durability, mainly in the area of the junction of the belt ends.21 cl, 4 dwg |
