摘要 |
A device for fabricating multi-layer tubing has a reservoir for tubing solution and discharges such solution from an opening in the reservoir bottom. The reservoir is suspended so as to remain level. Extending through the opening is a vertical rod of smaller diameter but itself suspended by a flexible wire so as to remain vertical. Material in the reservoir extrudes as an annulus even in cross-section by passing between the edge of the reservoir opening and the rod. Such extruded material hardens into one layer of the tubing. There is a repetition with a larger reservoir opening and so depositing a larger tube that is dried on and over the first tube. This is repeated as often as desired to get a finished tube of the proper inside and outside diameter. The method is following in succession the steps described above. |
