Sheet goods having extremely long repeat lengths and tiles having a large number of different visual patterns are formed by printing two different print patterns If the surface covering is a rotogravure printed sheet good, the repeat length will depend on the circumference of the print cylinders and the difference in the
Mar , The circular saw blade having a sharp bevel cutting edge provides a clean cut of the honeycomb core material at the surface to be cut invention relates to milling cutters for honeycomb core material, and more particularly, to a cutter assembly for machining honeycomb core surfaces to a close tolerance in
In joining two honeycomb core pieces in the direction of their length (L direction) we recommend that the outer marginal edge of each piece be overlapped with respect to the face surface area of its adjacent piece a minimum distance of about one full cell length of the material In splicing the pieces together in the direction of
Jan , In the present study, we have investigated the microheterogeneity of the core, corona, and peripheral regions of the F micelle using red edge excitation shift Soft template synthesis of honeycomb like ratiometric oxygen sensitive polystyrene nanospheres and their application in anti counterfeit
Apr , [ ]Dreadpiratemarc points points points months ago ( child) Engineer here Was it strong enough to walk on A perfectly flat aluminum sandwich with a foam or honeycomb core, my first thought is cabin floor material Just about every surface on the outside of an airplane is going to have a curvature
Contact smart cards having a document core, contactless smart cards including multi layered structure, pet based identification document, and methods of According to another aspect of the present invention, a smart identification document includes a core layer including a first surface and a second surface a first layer
Resistance to solvents is achieved by lowering edge penetration into the board so that the edges are hidden inside the casing of the seamed package or container or that they are turned onto its outer surface, or the edge of the board may be skived and thereafter folded double, so that the edge is closed.
The workpieces are cut and trimmed and are profiled at each of their edges in a single operation This is accomplished by means of two circular sawblades, which extend in a common plane and have interdigitating sawteeth, which preferably have diamond cutting edges The interdigitating sawteeth of the two sawblades
Sep , said flexible, non woven fibrous sheet material and said slit pattern, in combination producing an extendible sheet characterized by by the necessity for the slits to be close to being perpendicular to the edges of the web, so that during the expansion step, the expansion proceeds in a controlled manner.
The building material comprises a rigid core support material, a decorative outer surface layer, and a fiber based flame barrier layer positioned between the of form characterised by a discontinuous layer, i.e formed of separate pieces of material characterised by a layer of regularly arranged cells, e.g a honeycomb
Feb , Fourth, not only is the composite surface designed, but the tooling and moulding for the composite is just as intensive as the final part The aforementioned advances of material science in engineering of cellular solids, such as honeycomb core materials and foams, have resulted in the ability to design
Dec , A process as defined in claim wherein the strip is coined for fan folding by passing between a pair of rolls each having an axially extending anvil surface and an axially extending fold line forming edge, said anvil surface and said edge being angularly related, rotating said rolls to alternately present an
Unfortunately, near the edges or interface between the caul plates, pressure inconsistencies or misalignments may occur This results in The composite curing mandrel includes a surface, a plurality of anchors, a corresponding plurality of anchor clamps, a tensioning groove, and a tensioning device The surface receives
The top surface layer of the mover may consist of a friction layer or coating which would aid in the appliance staying in place on mover when being slid across hard surfaces of a finished nature In one embodiment, friction layer is a layer of open or closed cell foam in which the weight of the appliance would
For example, panels , , , , and may be constructed by layering one or more plies of fiberglass skin over each side of a Nomex honeycomb core The shell of the ), which could cause the upper end of the ladder assembly to contact and damage the edge of the access opening (FIG ) To prevent this
Tile segments in desired shapes are out with great precision utilizing a computer controlled laser and assembled on a previously prepared secondary backing with a sheet of hot melt adhesive material interposed between the assembly of segments and the secondary backing The hot melt adhesive is then heated to fuse
