Anchor device for anchoring a peripheral edge of a press blanket

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 for anchoring a peripheral edge of the press blanket, said anchor device comprising:

• a rotatable head defining a conical peripheral surface for supporting the blanket;
• a ring defining a concave surface which cooperates with said conical surface of said rotatable head such that the peripheral edge of the blanket is anchored between said conical surface of said head and said concave surface of said ring;
• a mechanism for urging said conical surface of said head axially away from the press shoe so that said conical surface moves towards said concave surface of said ring such that the peripheral edge of the blanket is wedged between said conical surface of said head and said concave surface of said ring the arrangement being 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 said conical surface of said rotatable head;
• said ring including:
• a first member which defines said concave surface;
• a second member extending from said first member and extending axially away from said conical surface;
• and
• a pin extending radially inwardly, said pin engaging a hole defined by the peripheral edge of the blanket.

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 for anchoring a peripheral edge of the press blanket, said anchor device comprising:

• a rotatable head defining a conical peripheral surface for supporting the blanket;
• a ring defining a concave surface which cooperates with said conical surface of said rotatable head such that the peripheral edge of the blanket is anchored between said conical surface of said head and said concave surface of said ring;
• a piston and cylinder mechanism for urging said conical surface of said head axially away from the press shoe so that said conical surface moves towards said concave surface of said ring such that the peripheral edge of the blanket is wedged between said conical surface of said head and said concave surface of said ring the arrangement being 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 said conical surface of said rotatable head;
• and
• a plurality of barbs extending away from said concave surface of said ring towards the peripheral edge of the blanket for assisting in anchoring the peripheral edge of the blanket against said conical surface of said rotatable head.
