A wheel (15) is freely mounted on the shaft (2) of a printing head and is in contact at its periphery with a film which is to be printed. A tachymeter (10) is provided which detects the speed of rotation of the wheel (15) and transmits a corresponding signal to apparatus (26) for controlling the speed of rotation of the motor (8).

An analysis test strip and a process for the production of analysis test strips with a longitudinal carrier upon which is fixed at least one test field. The test field material is produced batchwise in an amount sufficient for a plurality of test strips, and thereafter, in a chronologically separate working step, is continuously fixed in the form of at least one band onto a parallel-running substantially wider band of test strip carrier material. The band as a whole is cut up transversely to its longitudinal direction into a plurality of test strips. Prior to the cutting up, a bar code is applied to the carrier band running parallel to the edges thereof of such high information density that it is suitable as a store of batch-specific information necessary for the quantitative evaluation of the reaction which has previously been obtained by investigation of the test field material of one batch.
摘要:
There is disclosed a method for imparting a decorative or printed pattern to the surface of rotationally molded products during their manufacture. In this method, the decorative patterns are formed on a sheet film transfer as a coating of pigments dispersed in a hydrocarbon wax which overlays a release agent, such as a silicone coating on the sheet film. The decorative wax pattern is applied to a preselected area of an inside wall of the rotational molding cavity by positioning the transfer against the surface of the wall and burnishing the pattern onto the interior wall of the mold cavity. Thereafter, the particulate molding resin is charged to the cavity and the product is molded in a conventional procedure, resulting in transfer of the pattern as pigments incorporated into the resin, with most of the wax surfacing and being excluded from the product.

The air in a bag which has been filled with a content is first removed by pressing to flatten the surface of the bag. The bag is then transported and supported in such a manner that it assumes an arc shape having a fixed curvature with which the convex surface of the bag is permitted to be opposed to the convex surface of a printing plate at a position just below said plate. Under these conditions, the surface of the bag is clearly printed. The apparatus for effecting the printing method of the present invention comprises a pressing device for pressing the bag, a printing plate mounted on a plate cylinder of a rotary letter press and detector for causing the plate cylinder to be rotatively driven and the rotation thereof to be stopped.

A printing unit of a printing material processing machine, preferably a sheetfed offset printing press, includes a form cylinder and an impression cylinder. The form cylinder has a printing form for applying printed information to the printing material and the impression cylinder has a microstructured surface, preferably a cover, contacting the printing material. A surface of the impression cylinder contacting the printing material is provided with micro-embossed structures for applying embossed information to the printing material. The printing material is printed and embossed simultaneously. A security feature and/or a change in gloss can be implemented on the printed product through the use of the embossed, preferably micro-embossed, information.
摘要:
An offset printing machine having a first printing unit where an ordinary offset printing is achievable and a second printing unit where a number printing and perforating operations can be performed. The second printing unit has an impression cylinder independent of an impression cylinder of the first unit. The second unit is pivotally movable in horizontal plane with respect to the first unit. When the first and second units are connected to each other, offset printing process and subsequent numbering process are achieved. When the second unit is pivotted and is disconnected from the first unit, ordinary offset printing machine can be solely performed. A chain delivery section is provided in the first unit so as to transfer the printed sheet to the second unit. Tension control means is provided for controlling tension of the chain. Further, vertical and horizontal position fixing means are provided for fixing vertical and horizontal position of the second unit relative to the first unit.

摘要:
Printing apparatus especially useful for printing on the generally horizontal upper surface of the upper uninflated bag of a stack of generally flat, uninflated bags, while an inflated bag is positioned thereabove at the top of the stack for subsequently receiving a product therein.It includes a print head having a print face, preferably horizontally positioned, and print head carrier means for moving the print head from an inoperative position to a remote printing position along a curved path, its motion being initially away from the inoperative position, preferably in a generally horizontal direction, and finally toward the printing position in a generally perpendicular, preferably vertical, direction to the upper surface of the upper, uninflated bag for printing its upper surface.There may be included bag deflecting means for deflecting the inflated bag from the printing position to expose at least a portion of the upper surface of the upper, uninflated bag for printing thereon. The deflecting means may consist of an air jet mounted adjacent the print head for movement therewith to deflect the inflated bag in advance of print head movement.
