Abstract

The device includes a fixed outboard guide 10 for the widest-width paper strip and inboard guides 12 and 14 for strips of narrower widths. Guides 12 and 14 are pivotally mounted so that they are moved by the widest-width paper strip out of the path of travel of this strip.

Guiding Device for Paper Strips of Different Widths

The device includes a fixed outboard guide 10 for the widest-width paper strip and inboard guides 12 and 14 for strips of narrower widths. Guides 12 and 14 are pivotally mounted so that they are moved by the widest-width paper strip out of the path of travel of this strip.

The device includes a support member 16 to which guide 10 is fixed. Member 16 and guide 10 provide a concave surface 5 over which the strips travel. Member 16 is fixed to the side of a backing plate 18 which forms one aligning surface for paper strips traveling on surface 5, and outboard guide 10 has its highest portion 10a extending upwardly from surface 5 so that plate 18, portion 10a of guide 10 and member 16 form a U-shaped channel for holding the paper strip of widest width from moving laterally off surface 5 as the strip travels in direction A on surface 5.

Guides 12 and 14 are pivotally mounted on a support shaft 20, and spring fingers 22 and 24 are effective on guides 12 and 14, respectively. The paper strip of widest width therefore depresses and rotates pivotal guides 12 and 14 against the action of springs 22 and 24 so that all portions of them are below surface 5. The strip is propelled over surface 5 and is maintained in contact with this surface by suitable transport and pressure rolls.

When the paper strip of narrowest width is transported across surface 5 in direction A, springs 22 and 24 hold guides 12 and 14 in the positions...
