FIELD: machine building. ^ SUBSTANCE: apparatus consists of mandrel for pipe winding. The mandrel is tilted at angle to the side of pipe descent. Also value of angle corresponds to value 0<ëñÇ/2. The procedure consists in continuous winding material on the said apparatus. ^ EFFECT: increased resistance of mandrel to bending, reduced material consumption and weight of apparatus, increased strength characteristics and reliability, decreased area for apparatus installation, and reduced labour for removal wound item off mandrel. ^ 4 cl, 1 dwg |
