The invention relates to an apparatus adapted to apply a layer of viscous sticky material, particularly varnish, in the form of a pattern or otherwise, to a substrate. The apparatus comprises an applicator roll 1, and an impression roll 2, between which sheets 3 for printing are fed, by feed means. The means for applying the varnish to the applicator roll consist of a cylindrical screen stencil 8 with an internal squeegee device 9. The applicator roll is also displaceable so that it can be moved away from the impression roll 2 in the absence of a sheet to be printed in the event of a malfunction in the feed means.

Printing apparatus, particularly adapted to apply a varnish

A method and apparatus for fixing the binding agent of a dye-stuff to a printed web of material by means of heat applied to the web within a treatment or polymerization chamber. The treatment time of the web is increased by effecting a loop formation of the web upon a slowly moving belt traveling within the treatment chamber. After the web is first introduced into the chamber, it is then heated. Thereafter, the loop formation takes place. Upon leaving the treatment chamber, the web is passed over a stationary, curved shape heated plate, which smooths the web.

Method and apparatus for fixing a binding agent

An apparatus for the intermittent printing of material has at least one printing cylinder and an endless band for supporting the material to be printed. A portion of the band which is in printing engagement with the printing cylinder is supported on one side by supporting members and each supporting member is positioned opposite a printing cylinder. Each supporting member is movable transversely away from its respective printing cylinder. The pressure on the side of the band supported by the supporting member is less than the atmospheric pressure on the other side of the band so that when the supporting member is moved away from the printing cylinder the endless band will remain in contact with the supporting member and thus be spaced away from the printing cylinder.

Apparatus for intermittent printing

A supporting structure for a stencil in a rotation screen printing machine. The stencil includes a thin-walled perforated cylinder having at both ends a ring secured via an annular connecting area to an extremity of the cylinder. The machine includes two opposite stationary parts each with an internal rotatable sleeve for connection with the end rings of the stencil, an aligning bearing within each part for supporting the sleeve, an universal joint element being provided in the supporting end structure of the stencil.

Compensating rotary screen supports

A cylindrical stencil for screen printing consisting of a perforated thin-walled sleeve with a rigid end ring at both ends; each of said rings being connected to a supporting member via a connection excluding any play in rotational direction, said connection comprising a member of plastically deformable material.

Plastically deformable, inelastic stencil end ring connection

A rotary screen printing machine comprising a plurality of rotatably mounted cylindrical screen stencils each having an internal squeegee blade supported in a holder, means being provided either in the mounting of the stencil or in the support of the squeegee blade for obtaining a uniform angle between said blade and the stencil along the entire length of said stencil.

Means to provide uniform lengthwise squeegee angle of attack

A rotary screen printing machine of the type including at least one cylindrical stencil is provided with a squeegee blade for each stencil to force a printing paint or paste through apertures in the stencil onto a textile web or sheet of paper. The squeegee blade comprises a thin flexible resilient metal strip having a thickness less than 1% of the width of the portion of such strip protruding from its holder. One edge of the squeegee blade is attached to a squeegee holder and the other or trailing edge of the blade contacts the inner face of the stencil. A covering layer of a synthetic plastic may be provided on the surface of the blade directed toward the inner face of the stencil.

Thin flexible metal squeegee blade for rotary screen printer

A squeegee device for a cylindrical stencil comprising a fitting and a thin flexible strip has one edge secured in said fitting. The opposite free edge of the flexible strip has a rigidifying, reinforcing member thereon, such as a cylindrical rod which is in contact with the inner wall of the stencil.

Squeegee device

A method and device for transferring from a dye supporting strip a design to a textile web under the action of heat and a sub atmospheric pressure, the strip being pressed against the web by a difference in electrostatic charge. A charging device is used adapted to direct a very narrow beam of electrons upon the strip.

Method and device for dye transfer printing

A method and apparatus for printing cloths in a rotary screen printing machine comprising a number of driven cylindrical stencils, the cloths being interconnected by intermediate strips formed from uninterrupted warp threads so as to constitute a continuous web; a special feeder is mounted before the printing machine, said feeder having means cooperating with said strips, said means being synchronized with the rotation movement of said stencils.

Cloth printer and method with feeder engaging warp threads

A device for applying a layer of a viscous substance upon a travelling belt, comprising a perforated spraying tube and a squeegee blade, said blade having a curved shape with its convex side turned in the direction of travel of the belt.

Device for applying a layer of a viscous substance

A rotary screen printing machine comprising a travelling endless belt and at least one thin-walled cylindrical screen stencil for cooperating with the material to be printed which is supported upon the upper horizontal flight of said belt. A pressure roller and an elastical smoothing blade are arranged above the belt for cooperation with the material in an area lying before the first screen stencil.

Rotary screen printing machine

A paint feeding element to be used in a cylindrical screen stencil machine, said element being composed of an oblong reservoir connected to a paint supply and two converging rigidly-resilient thin strips forming a mouth piece for contact with the inner wall of a stencil, both strips enclosing a steep angle with said wall.

Pressurized squeegee with stiff resilient sealing strips

A rotary screen printing machine has a number of cylindrical stencils each with an internal squeegee and at least one stencil has an impermeable area parallel to the center line of the stencil. The squeegee of the said stencil may be raised or lowered while the impermeable area is in contact with the material being printed such that the printing action may be interrupted during one or more revolutions of the stencil during continuous operation of the printing machine. The stencil will print only when the screen portion is in contact with the material and the squeegee is lowered. A pattern can thus be printed which has a repeat length greater than the circumference of a stencil.

Method and device for printing a web or a rectangular piece of material

A device for uncoupling and thereafter recoupling both ends of horizontally travelling bars to a conveyor consisting of two parallel chains. Each chain is provided with a great number of supporting means composed of an unmovable first member and a rotatable second member capable of receiving and temporarily retaining an end of a bar and of releasing said end again. The locking and unlocking of the end of the bar is rendered possible by a rotational movement of said second member caused by four stationary abutments along the path of the advancing conveyor chains.
