There is provided a simple-structured and inexpensive device for stacking a successive separator and sheet electrodes which can protect an end portion of a sheet electrode when folding the successive separator, and which enables smooth folding of the separator to improve the productivity. The device comprises a stacking stage 10 which adsorbs and holds a leading end of the tape-like separator S, and on which sheet electrodes P, N and the separator S are successively stacked, separator reciprocating means for reciprocating the tape-like separator S on the stacking stage 10 with the stacking stage 10 being as a center, and a folding guide member 20 which comes close/moves apart relative to the stacking stage 10, covers both side ends of the stacked sheet electrode P, N in the moving direction of the separator S, and guides folding of the separator S accompanied by a reciprocal movement of the separator S at both side ends of the sheet electrode.

Die Erfindung betrifft einen Gebrauchstuchvorrat (5) bestehend aus einem Vorratsstreifen (1), der zick-zackförmig an quer verlaufenden Faltlinien (4) zu aufeinanderliegenden Streifenabschnitten (1a) gefaltet ist. Er weist in Längsabständen (L) voneinander quer verlaufende Schwächungslinien (3) auf, an denen jeweils ein Gebrauchstuch (2) abreißbar ist, wobei die Schwächungslinien (3) zwischen den Faltlinien (4) angeordnet sind.
摘要:
Apparatus for folding a continuous strip (1) of material such as paper or the like, comprising a pair of mutually parallel and counter-rotating cylinders (10) between which said continuous strip (1) of material is fed and which are provided internally with respective devices (20) for gripping and means (30) for deviating the strip (1) towards the said gripping devices, both being operated by associated actuating means (21,22,23,24) from a non-operative position into an operative position, wherein said means (30) for deviating the continuous strip (1) and said gripping means (20) are totally inset within the side surface (10a) of the respective cylinder (10) in the respective non-operative position.
摘要:
Machine for drawing out a web of a roll comprising a trolley (1) carrying a roll of textile web (2) which can travel the length of a table (3) on which the textile is drawn out, the said trolley (1) having two side upright members (4,5) fitted with wheels (6,7) and joining bars (6a,7a) uniting the the side uprights (4,5) and also including at least one textile feed roller (8) with its corresponding guide tubes (9) and a cutting module (10) or a Zig-zag folding module (11). The manual advance cutting module (10) can be converted to a motorized cutting module by attaching a composite assembly (22) which includes, fitted to one single profile member (23) a motor (24) and a belt and and pulley drive (25 and 26). The automatic loading device (40) includes two motors (45,46) for raising the roll (2) and a motor (41) for actuating the travel laterally along the joining bars (6a,7a). One of the uprights (4) of the trolley (1) is provided with orifices (60,62,63,64 and 65) for attaching and coupling up the operating motor (61) and both the uprights (4,5) have therein housings ( 66,67 ) for the bearings of the drive shaft (68). The trolley (1) converts from manual to motorized operation by attaching the motor (61) with its drive assembly (66 and 131 - 137) without the need for further mechanical modification. The improvements also refer to a drive unit from the motor (61) to a feed roller (8), a unidirectional bearing in one of the two feed rollers (8, 35), a turbulence protection device (85), a device for the quick hooking on of the cutting module (10), a textile tensioning device (84), a horizontal movement pantograph unit (109-112), a travel limiting flange (32) for the Zig-zag folder clamps (12, 13), a connector guide bar (123) and a flexible tube (124) for connecting the power supply to the cutting module (10). Permits a progressive modular assembly.
摘要:
There is disclosed apparatus and method for folding webs which includes a pair of rolls (10,11) each having tuckers (12) and grippers (13) arranged for tucker-gripper coaction and wherein the tucker (12) is free floating within its mounting advantageously of the order of 1/16" movement in a circumferential direction.
摘要:
Die zu faltende Materialbahn (23) wird durch eine Durchtrittsöffnung (10) hindurchgeführt, die durch zwei Walzen (6, 7) festgelegt wird. Letztere sind frei drehbar in einem Schlitten (2) gelagert, der unterhalb des Stapels (21) hin und her bewegbar angetrieben ist. Ueber diese Umlenkwalzen (6, 7) sind Bänder (13, 14) geführt, welche an beiden Enden (15, 16; 17, 18) an einem feststehenden Gestell (1) befestigt sind. Diese Bänder (13, 14) sind weiter S-förmig über zwei weitere Umlenkrollen (8, 11; 9, 12) geführt, von denen jeweils die eine (8, 9) ebenfalls drehbar am Schlitten (2) und die andere (11, 12) ortsfest im Gestell (1) drehbar gelagert ist. Unterhalb der Durchtrittsöffnung (10) ist eine Rücklaufbremse (32) angeordnet. Bei der Hin- und Herbewegung des Schlittens (2) wird die Materialbahn (23) zickzackförmig gefaltet, wobei gleichzeitig die einzelnen Materialbahnabschnitte (22) von unten an den Stapel (21) angelegt werden.
