Abstract:
Die Registereinzugsvorrichtung für Bogen-Prägedruckmaschinen mit Positionssensoren (S1, S2, S3) zum Erfassen von Druckmarken (P1, P2, P3) eines Bogens (5), weist eine abschwenkbare Registerplatte (15) als Anlegetisch mit Entlüftungsöffnungen (20) und Vakuumzuleitungen (21) an eine Saugvorrichtung (22) und absenkbare Frontanschläge (12) und Stellglieder (L1, L2, L3) zum Positionieren der Registerplatte in X-Richtung und in Y-Richtung auf. Mit einer Registersteuerung (11) wird die Registerplatte (15) abgeschwenkt, ein Greiferbalken (8) herangeführt, die Registerplatte wieder aufgeschwenkt, dann ein Bogen (5) zugeführt und an den Frontanschlägen (12) gestoppt. Dann wird die Registerplatte evakuiert zum Ansaugen und Fixieren des Bogens auf der Registerplatte. Dann werden die Positionen der Druckmarken (P1, P2, P3) durch die Positionsmarken erfasst, daraus die Registerkorrekturwerte (X1, X2, Y3) berechnet und die Registerplatte durch die Stellglieder (L1, L2) in X-Richtung und durch das Stellglied (L3) in Y-Richtung in die Soll-Position (P1S, P2S, P3S) bewegt. Dann wird der Bogen durch den Greiferbalken erfasst, die Registerplatte (15) belüftet und der Bogen vom Greiferbalken weitertransportiert. Dies ergibt eine automatische Registerkorrektur bei hohen Maschinengeschwindigkeiten und mit höchster Druckqualität.

Abstract:
Herein are disclosed methods for liberating one or more packaged devices from a packaging web, and a dispenser for performing such methods. The packaging web is separated into first and second waste webs which are co-wound onto a common collection spool.
Abstract:
A unit (1) for applying first and second tabs (100, 101), obtained respectively from a first continuous web (103) and a second continuous web (104), to a chassis web (102), comprises an applicator drum (2) rotatable about an axis of rotation (R2) and comprising a main body (3); a plurality of carriers (4, 5) movable between a lowered position close to the axis of rotation (R2) and a raised position away from the axis of rotation (R2) and each comprising at least one suction portion (7, 8); a first carrier (4) comprises a first suction portion (7) and a first non-suction portion (9) aligned along the axis of rotation (R2), a second carrier (5), following the first carrier (4), comprises a second suction portion (8) and a second non- suction portion (10) aligned along the axis of rotation (R2), the first suction portions (7) being alternated with the second non-suction portions (10) and the first non-suction portions (9) being alternated with the second suction portions (8); the unit comprises a plurality of anvils (11), each interposed between a first and a second carrier (4, 5); the unit (1) comprises a first system (22) for holding down the first web (104) on the applicator drum (2) located upstream of a cutting device (12) for cutting the first and second webs, and a second system (23) for holding down the second web on the applicator drum (2) located upstream of the cutting device (12).
Abstract:
An Off-Road Rolling Film Vision System has a Controller Module, a Takeup Module, and a Rollout Module that are attached to an off-road vehicle handlebar. The Controller Module has a Command Input, a Controller Process Module, a Command Transmitter, and a Power Supply. The Controller Module remotely controls a Motor in the Takeup Module. The Command Input has at least one Button to accept a knuckle bump for controlling the Motor. The at least one Button may be adjacent to a user's metacarpophalangeal index finger joint, or to a user's metacarpophalangeal thumb joint or both. The Takeup Module has Compartment, a Takeup Spool Compartment, a Takeup Spool Gear Compartment, a Takeup Film Window, a Motor, a Motor Gearbox, and at least one Takeup Spool Gear.
Abstract:
The object of the invention is an escapement gear wheel, wherein the shape of the teeth (21, 21', 22, 22') is chosen such that the straight line between the tip of a tooth (21, 21', 22, 22') and the centre of the escapement wheel (2) is fully enclosed within the escapement wheel (2). Further the object of the invention is an element rotation control mechanism, comprising an escapement gear wheel fixed at the element's axis of rotation and an anchor pivotably mounted at a distance less than half of the span of its arms from the escapement gear wheel (2). The anchor can come into contact with the escapement gear wheel with the first (11) or the second (12) arm. The span of the anchor's arms (1), the radius of the escapement wheel (2) and sized and the number of the teeth (21, 21', 22, 22') are chosen so that in the position of the escapement wheel (2), where one of the arms of the anchor (1) has a point of contact with the escapement wheel (2) located exactly at the bottom of the inter-tooth notch, the point of contact of the second arm of the anchor is located at the rear edge of a tooth (211, 211', 221, 221'). The object of the invention is also an element rotation control method, wherein the mechanism according to the invention is mounted to the element in the element's axis of rotation.
Abstract:
A digital printing method is provided in which a segmented static print table normally supports the working area during printing. For enabling borderless printing or printing on a mesh material the step is included of reconfiguring the static printing table by removing and replacing segments of the table and replacing them bucket segments or by a gutter part to collect jetted ink passing through or aside the medium. This avoids contamination of the static print table leading to smearing and bad prints.
Abstract:
A step-wise medium transport system is provided having high accuracy for transporting recording media in a digital printer, - the medium is transported using accurately moving tables to which the medium is attached - during printing steps the working area of the medium, on which the printing is done by the printer, is at all times fully supported by a static table avoiding disturbances.
