Abstract

The present invention relates to apparatus for the continuous enamelling of tubes. The apparatus disclosed incorporates an upender which is installed with provision for displacement along guides so as to transfer pipes from a horizontal position into a vertical one. These guides are arranged in vertical parallel planes, at least one guide in each plane, and each of the guides consists of several portions: a horizontal portion, an inclined one, and a portion running vertically so as to transfer the tubes to a trolley located on an annular splitable monorail which is made up of immovable sections and movable ones which displace in the vertical plane integrally with the tube during the process of enamelling. The apparatus also incorporates a means of applying enamelling slip and a means of heating designed to dry and fuse the slip. The apparatus disclosed displays a high capacity and allows to apply the slip to tubes of various lengths and diameters.

Claims3

Dependent claims

An apparatus for the continuous enamelling of tubes comprising:

a conveyor for feeding the tubes, an upender in the form of a boom with grippers which serve to receive the tubes from said conveyor and transfer them from the horizontal position into a vertical one, and is installed with provision for displacement;
guides placed whereby said boom of said upender are in vertical parallel planes, having at least one guide in every plane and consisting each of more than one portion;
a first of said portions running essentially horizontally;
a second portion contiguous with the first one and extending at an angle to the horizontal, a third portion running essentially vertically so that the tube is transferred from the horizontal position into the vertical one, a trolley for receiving the vertically arranged tube which rests on a monorail made up of immovable and movable sections, said movable sections of said monorail, displacing vertically and integral with the tube in carrying out the process of enamelling, means for applying the enamelling slip to at least one side of the tube, and means for heating to dry and fuse the enamelling slip.
