wawm-i, county of have' @tiers fm 01' in Close proximity in the point of pointv the fibrous sheet or layer e is subjected to the greatest compression, and the cutting edge acts tangentially With'relation to the pattern and severs the portion of the sheet or layer which is projected from the under surface thereof into the mold, which is 'brought into the line ofy greatest compression, said cuttingr edge forming a closure for said mold as the pattern is moved ltoward the knife, and the upper beveled surface of said cutting' edge also serving to iron, glaze orcs,

ender the cut portion of. the under surface of the sheet or layer, whereby the design formed by the cut portion of the under surface is sharply defined with relation to the uncut portion of the same Surface.

'lhe long-er beveled or curved'surface let of the knife enables the cutting edge to be made thin, so as to be brought to or in close proximity to the point of greatest compression, while at the same time a substantially large clearance is obtained between the upper roll l and the knife for the free passage of the sheet or layer, and also to avoid contact of the upper roll With the knife.

The shorter beveled or curved surface `en ables the knife to be of su'llicient thickness at or near the cutting edge, to obtain the desired strength in the knife at the cutting edge so as to avoid breaking of the same.

ln Fig. l, the pat-tern is shown in the roll b, which is located below thefbrous sheet or layer e, but it is' `not desired to limit the invention in this respect, as the pattern may he located above'the sheet or layer and may be separate from its backing roll, as shown in Fig. 2, wherein the molds a are shown as formed in a strip or piece 20, which may be made of Celluloid, metal or other suitable material, and the backing roll is made plain and engages the upper surface of the pattern strip.

. The machine herein shown is especially adapted for forming' a design in aY surface of sheet or layer of material composed of fibers of different grades or kinds, such as a skin, or in the surface of a sheet or layer `composed of the same kind or grade of liber, such for instance as felt, and in the case of the latter, the design is sharply defined by the cut portions of the surfaces, Whose fibers p 30, Fig. 3, are ironed, calendered and com-v pacted tol give a materially firmer and distinguishable appearance than the uncut por- A.tion 3l of the surface.

l Claimsy l. A machine for the purpose specified comprising a pattern vroll provided on its un 1,070,51 i

surface with mplurality of wells or recesses forming molds, a pressure roll coperatin with said pattern roll, to force portions o one surface of a 'sheet or 'layer of fibrous matenial into said molds, and a knife having nclined sides of unequal length which form a.

,substantially thin cutting edge extended be- .2. A machine for the purpose specified, 7o

comprisinga movable pattern surface having a plurality of Wells or recesses forming molds, a1 pressure member coperating with.

said movable pattern to force portions of a ,fibrous sheet `or layer into said mold, and a knife having inclined sides of di'erent length to form a thin, cutting edge which is arranged to close the mouth of the mold and cut off from the surface of a sheet or layer of fibrous rmaterial the portion thereof so Which is projected into the mold at or near the point of greatest compression, substantially as described.

1 3. A machine for the purpose specified,

comprising a movable pattern surface having a plurality of Wells' or recesses forming molds, a pressure member cooperating with said movable pattern to force ortions of a fibrous sheet or layer into sai molds, and

a knife having a short and a long side forming acutting edge, the longer side extending below the median line of the knife to form a thin cutting edge which forms a closure for the mouth of the molds, substantially as described.

4;. A machine for the'purpose specified, comprisingv Ia movable pattern-surface having a plurality of Wells or recesses forming molds, a vpresser member cooperating with said movable pattern to forceportions of a fibrous sheet or layer into said molds, and a knife having a substantially thin cutting edge interposed between said pattern surface `and the surface of the sheet or layer Whose portionsarc forced into the molds and eX- tended to substantially the point of greatest compression and forming a closure for the .mold near the point of greatest compression. In testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses.
