ZCIaims.
A process for the manufacture of continuous plain and corrugated sheets ci 'asbestos cement with reenforcement of iron wire netting is known, consisting in the mixing of cement and asbestos in a certain proportiomtogether with water and coloring matter, to a thick paste, applying this paste to both sides'of an iron wire netting, pressing the paste and netting a plurality of times by water permeable means to force the paste against,
..10 through and around the meshes of the iron netf ting to remove the excess water, rolling the sheet to the desired thickness, drying the sheet to nearv ly complete dryness, con'ugating the sheets by rst rolling two corrugations into the middle of 15` a sheet and then continuing rolling other corru- Sations on either side of the middle of the sheet in such a manner that the plate. is corrugated progressively throughout its whole length, and nally cutting the sheets into desired lengths.
2o In this known process, .the reenforcing sheet with, the mixture of asbestos cement is passed through the rolls downwards, in such a manner that a large quantity oi' water is carried through the pressing rolls and consequently it is rather 25 difficult to obtain the desired thickness together with the exact degree oi wetness.
According to the Apresent ,invention the reenforcingsheet with the mixture of cement and asbestos is moved upwards to and through the the paste applying rolls, so that even before the sheet with the mixture oi asbestos cement passes through the pressing and smoothing rollers, a large quantity of water will be removed.
35 For this purpose, the casing containing asbestos cement is located under the press rollers.
The reeniorcing sheet is passed through said casing between a plurality of pairs oi horizontal rolls,
40 under the mixture level. Before the reenforclng sheet with the asbestos cement passes to the pressing and smoothing rollers, excess water is separated vfrom the asbestos cement, partly by 45 its own gravity and partly by the action of guide f rolls.
For the purpose of explaining the process according to the invention more clearly, reference is made to the accompanying drawing in which:
e0' Fig. 1 is a diagrammatic sectional elevation of arranged one behind the other, said rolls being 4provided with two or more pairs of horizontal rolls 3, arranged one behind the other, the shells of said rollers being of wire netting. v'Ihe rollers 3 are mounted in such a manner that either both or one of the two rollers oi each pair of rolls may be moved to adjust the distance between the shells, and means may be provided to adjust the distances in connection with all the pairs simultaneously and during working.
The reenforcing sheet 4 passes over guide rollers 5 and then between the pairs of rolls 3, said rolls 3 beim entirely coated with the mixture oi' asbestos cement.
Allthese pairs of rollers 3, 3 force a layer oi 2o the-mixture of asbestos cement upon and against the. reenforcing sheet 4. The sheet then passes through a pair of press rollers 6 and through the rollers 'l to the main press rollers 8. It will be seen that from the point of delivery of the rollers 3, 3 the sheet moves in an upward direction.
If it be desired to manufacture twoor multiply sheets of asbestos cement a second like machine may be placed on the other side of the main press rollers 8, and the rollers 8, 8 may be 30 used to combine two continuous sheets to one unit.
n In case several sheets are to be united, it will be obvious that two-or more pairs of feeding rollers, for instance, one above the other, are to be provided. 4
I claim:
l. A method of making continuous sheets oi asbestos cement reenforced with iron wire netting consisting in passing wire netting through a casingv containing asbestos cement i'n a substantially horizontal direction through a plurality oi pasting rollers having shells vconstructed of wire netting and subsequently passing the pasted sheet in an upward direction to and through pressing rollers substantially as described.
2. A method of making continuous sheets oi asbestos cement reenforced with iron wire netting. comprising in st eps: passing iron wire netting through a casing containing asbestos ceaosasos ment in a substantially horizontal direction successively between pairs of pasting rollers having shells constructed of wire netting, whereby a reenorced sheet of asbestos cement is formed in the casing; passing said sheet between a pair `of pressing rollers having shells constructed of Wire netting; passing saiol sheet between a further pair of rollers; and then passing said sheet in a substantially vertical direction between another pair of pressing rollers having shells constructed of Wire netting, substantially as described.
