Abstract:
A marking device (10) comprises a frame (1) (of frame plates (12, 14)) to which are fixed first and second motors (16, 18). A carriage frame (40) is pivoted in the frame about a screw axis (22). A marking head (30) is mounted on the carriage frame for movement in a direction parallel the screw axis. A drive screw (20) is rotationally mounted in the frame along the screw axis and is driven by the first motor (16). The carriage frame is journalled on said drive screw to permit said pivoting about the screw axis. The marking head is driven by rotation of the screw, the carriage frame being pivoted by the second motor. The carriage frame (20) comprises a bar (32) on which the marking head slides. The bar is disposed parallel the drive screw. The bar has at each end an arm (34, 36) pivoted on bearings (35, 37) on the drive screw. One arm (36) has an extension (66) fixed to a belt (58) disposed around two idler pulleys (62, 64) and a motor pulley (60) driven by the second motor. The extension has a contact surface (68) having a curvature centred on the drive screw and having both radius and circumferential extent that is sufficient to approach contact with the belt around the idler pulleys. By this means, the tension of the belt is maintained throughout its pivoting of the arm extension (66).
Abstract:
Elastomeric stamps facilitate direct patterning of electrical, biological, chemical, and mechanical materials. A thin film of material is deposited on a substrate. The deposited material, either originally present as a liquid or subsequently liquefied, is patterned by embossing at low pressure using an elastomeric stamp having a raised pattern. The patterned liquid is then cured to form a functional layer. The deposition, embossing, and curing steps may be repeated numerous times with the same or different liquids, and in two or three dimensions. The various deposited layers may, for example, have varying electrical characteristics, interacting so as to produce an integrated electronic component.

An apparatus and methods for the adjustment of the position of a die in a printing press are disclosed. The apparatus and methods provide for the adjustment of a die frame within a chase. The chase defines a horizontal and a vertical axis. The die frame is slidably secured in a chase to permit movement and adjustment of the die frame in the horizontal and the vertical axis. The die frame may be slidably mounted to one or more vertical guides and one or more horizontal guides to facilitate movement and adjustment in the horizontal and vertical axis.
Abstract:
The present invention is generally directed to a process for hot embossing a base sheet and/or to a process for perforating and bonding multiple plies of a paper product together. The process can be used in order to apply a decorative pattern to a paper product and/or to bond multiple ply products together. In one embodiment, the process of the present invention includes feeding a previously formed single ply or multi-ply base sheet through a heated embossing nip. As the base sheet passes through the heated embossing nip, sufficient heat and pressure is imparted to cause the fibers within the sheet to begin to melt or glassinate. Upon cooling, inter-fiber bonding occurs resulting in a well-defined embossment as well as bonding between plies of a multi-ply product.
Abstract:
This invention relates to a relatively thin cladded graphic arts impression graphic arts impression die plate (20) having a steel layer (22) which is integral throughout the extent thereof with a layer of copper (24) or bronze. A relieved design-defining surface may be formed in the copper or bronze layer by a chemical etching process or by chemical milling. In the case of chemical etching of the graphic arts impression die plate (20), a design-defining layer of photo-resist is applied to the outer surface of the copper layer (24) or the bronze layer and the relieved design is formed in the copper or bronze layer using a conventional ferric chloride etching solution. The etched graphic arts impression die plate may be mounted on an etchant-resistant backing or magnetic support member (28) to present an assembly which increases the thickness of the die assembly sufficiently to permit use thereof on standard stamping and embossing equipment without modification of the die-supporting chase. The magnetic support member (28) has a plurality of pairs of permanent magnets (33, 35) each pair of which is embedded within a respective cavity (32) and that are magnetically bridged by a steel plate 36. The pairs of magnets (33 and 35) attract the steel layer (22) of the graphic arts impression die plate (20) and thereby hold the graphic arts impression die plate on the magnetic support member (28). Etching of a blank cladded metal graphic arts impression die plate (20) is facilitated by provision of a rotatable magnetic support member (64, 164, 264, 364) within die etching apparatus (40) which serves to support the die blank while it is being subjected to the etchant solution. The die blank magnetic support member (64, 164, 264, 364) has permanent magnets (78, 178, 278, 378) embedded therein, or alternatively pairs of magnets each pair of which is bridged by a steel plate, which magnetically attract the steel layer (22) of the graphic arts impression die plate (20) to affix the graphic arts impression die plate to the magnetic support member.
Abstract:
The invention relates to the assembly of a carriage for driving a marking apparatus on at least one guide member, said carriage being fast with a bearing allowing the carriage to slide on the guide member. There is made in the carriage at least one opening made with transverse dimensions substantially greater than those of the guide member; the carriage is placed in the precise position that it must occupy; an intermediate space is thus defined between the walls of the opening and the opposite outer periphery of the guide member; this intermediate space is filled with a polymerizable resin and, by polymerization of this resin, a sleeve is formed between the walls of the opening and at least a part of the outer periphery of the guide member.
Abstract:
A flexible counter for an embossing system provides resilient support under a sheet which opposes pressure from a contoured die forming an embossment in the sheet. The flexible counter includes a resilient mat and a fixed bolster which supports the mat. The bolster has a peripheral wall which extends around sides of the mat so that an upper portion of the mat protrudes above the peripheral wall. In addition, the bolster includes support surfaces bounded by recesses. The support surfaces support a bottom surface of the mat, and the recesses receive bulging portions of the mat when compressed under pressure from the die.
Abstract:
A hot stamping cylinder for webs includes a mounting cylinder, a longitudinal channel extending running along the substantial entirety of the length thereof. A flexible substrate plate includes a leading edge flange substantially parallel to the flexible substrate plate and offset a distance substantially equal to the depth of the channel. A trailing edge flange is also provided which is substantially parallel to the flexible substrate plate and offset a distance substantially equal to the depth of the channel. A layer of silicone material is positioned on the flexible substrate plate where the layer of silicone material has a relief pattern thereon which corresponds to a desired stamping pattern. A longitudinal clamp resides in the channel and retains the leading edge flange and the trailing edge flange within the channel thereby securing the substrate plate, with silicone relief pattern thereon, to the mounting cylinder in preparation for use in a web hot stamp operation.
