摘要:
The invention relates to a device for automatically unwinding web-shaped materials (8) from a parent roll (3) and to a method for operating such a device. The device comprises an input arm (2) and a first drive unit (6), wherein the parent roll (3) is rotatably supported on the input arm (2) by means of a winding core (4) of the parent roll and the first drive unit (6) serves to apply a driving force to the parent roll (3). In order to achieve high productivity, the unwinder (1) has a removal arm (13), with which a second drive unit (14) for applying a driving force to the parent roll (3) is associated, wherein the parent roll (3) can be transferred from the input arm (2) onto the removal arm (13) during an unwinding process. The material web (8) is then unwound from the parent roll (3) supported on the input arm (2) down to a specifiable minimum diameter, wherein the parent roll (3) is then transferred onto the removal arm (13) during the ongoing unwinding process and is actively unwound further there, wherein a new parent roll (3') is received by the input arm (2). Thus, uninterrupted unwinding is enabled.

A device (1) for feeding self-adhesive or "pressure sensitive" labels to a labelling machine comprises a frame (2) and supporting means (3) comprising a supporting plate (17) for supporting a reel (4) of web (5) with labels applied to it, and also comprises at least one guide element (28, 29) designed to be at least partly inserted in a central hole (7) of the reel (4) which can rotate about it. The device (1) also comprises a detaching station (8) for detaching the labels from the web (5), feeding means (9) for feeding the web (5) to the detaching station (8) and recovery means (10) for recovering the web (5) without labels. The supporting plate (17) is removably associated with the frame (2) and the supporting means (3) also comprise a containment head (30) switchable between an open configuration, in which it allows the coupling with and uncoupling from the frame (2) of the supporting plate (17), with the reel (4) placed on it, and an operating configuration, in which it allows the reel (4) to be held between itself and the supporting plate (17), allowing reel (4) rotation.

A printer cartridge (12) suitable for use in a cartridge-based printer (10) houses and dispenses a roll of label media (14). The cartridge includes housing (28)having a top wall (30) and a bottom wall (32). A yoke (42) pivotally mounted between the top and bottom walls for pivotable movement about a pivot axis (103) includes a label media supply shaft for holding a roll of label media. The label media supply shaft has a longitudinal axis spaced from, and parallel, to the pivot axis. A label media drive roller (46) is rotatably mounted between the top and bottom walls, and a biasing means (44) biases the yoke (42) toward the label media drive roller to maintain the roll of label media in contact with the label media drive roller (46) and defines beginning of a media path. In one embodiment, the yoke is adjustable to accommodate different label media widths.

摘要:
A miniaturized rolled-paper holding mechanism (10) which is capable of detecting the residual quantity of rolled-paper in both horizontally and vertically installed states of a printer. The rolled-paper holding mechanism (10) includes a rolled-paper holder (21), a holder cover (41), a positioning member (51), and a residual-paper-quantity sensor (61). The positioning member (51) is structured such that, as the holder cover (41) is opened or closed, the inclination angle of the positioning member (51) is varied with respect to a second-bottom-portion inclined surface (29) formed in the rolled-paper holder (21). Further, a second positioning groove (31) -which, when the holder cover (41) is closed, can be contacted with rolled-paper R having a given diameter- is formed between the positioning member (51) and the second-bottom-portion inclined surface (29) of the rolled-paper holder (21).
摘要:
The invention concerns a method and device for winding up a continuous web of paper (9) onto a reel-spool (11), as large a part as possible of the resultant wound roll (12) having a high degree of winding hardness (WH). The invention is characterized in that a relatively soft intermediate layer is formed between the wound roll (12) with a high degree of hardness and the winding core (11). For this purpose, it is ensured in a brief initial phase of the winding-up process that the winding hardness (WH) is relatively slight in the innermost layers of the wound roll (12). Subsequently, there is an immediate transition to a relatively high winding hardness (WH) which is substantially maintained during the remainder of the winding-up process. Alternately, the relatively soft intermediate layer can also be formed as a result of the reel-spool (11A-11D) comprising a soft covering (41, 42, 43, 44, 45, 46, 47) on a metal reel-spool body (40).

Bei einem Verfahren zur Bestimmung von immanenten Kräften einer in Tragarmen eines Rollenträgers aufgeachsten Vorratsrolle sind die Tragarme mit einer Anzahl von Meßwertaufnehmern versehen. Die ermittelten Ergebnisse werden einem Rechner zugeleitet welcher nachfolgend nach Eingabe der Breite sowie des spezifischen Gewichtes der Materialbahn die Länge der Materialbahn ermittelt. Zur Durchführung des Verfahrens ist eine Einrichtung vorgesehen.
