Anchor device for anchoring a peripheral edge of a press blanket

Abstract

In an enclosed shoe press having a press blanket extending through an extended nip defined between a backing roll and a press shoe, an anchor device is disclosed for anchoring a peripheral edge of the press blanket. The anchor device includes a rotatable head which defines a conical peripheral surface for supporting the blanket. A ring defines a concave surface which cooperates with the conical surface of the rotatable head such that the peripheral edge of the blanket is anchored between the conical surface of the head and the concave surface of the ring. Also, a pin extends radially inwardly from the ring, the pin engaging a hole defined by the peripheral edge of the blanket. Additionally, a plurality of barbs extend away from the concave surface for assisting in anchoring the peripheral edge of the blanket against the conical surface of the rotatable head. A mechanism is provided for urging the conical surface of the head axially away from the press shoe so that the conical surface moves towards the concave surface of the ring such that the peripheral edge of the blanket is wedged between the conical surface of the head and the concave surface of the ring. The arrangement is structured such that when the blanket extends through the extended nip and during subsequent flexing of the blanket, the peripheral edge of the blanket is firmly anchored to the conical surface of the rotatable head.
