Worth FOR BROOM AND DEVICE FOR MANUFACTURING

摘要

The invention relates to a pile of polymer materials for brooms and means of molding of thermoplastic materials. Technical result of utility model - improving the cleaning properties of the pile, convenience and reliability of the pile beam assembly in a broom, making a wide range of pile, pile manufacture of a wide range. Worth 1 broom made of thermoplastic and has an oval cross-section with double corrugation on its broad surface formed in the form of protrusions 2 of height (h) from 0.1 to 0.5 millimeters, longitudinally extending length. An apparatus for manufacturing pile includes an extruder 3, a first pulling yarn from thermoplastic node first broach assembly comprising upper and lower rollers 4, 5, the first and second stationary rollers 6, 7, mounted on a support 9, a node of the second broaching comprising first and second drive rollers 10, 11 with the drive 12, the cutting mechanism 13. The upper roller 5 is biased, and the bottom roller 4 is formed with an annular radiused recess 14 for forming the circular cross-section yarn and a variable frequency drive 15 for controlling the first draw rate. In each node of the second broaching drive roll 10, 11 is knurled. Worth has improved cleaning properties in the beam broom and due to the additional coupling projections corrugations securely fixed in center pole broom, providing increase of its longevity. A method and apparatus producing corrugated pile are simple, economical.
