BLANKET TENSIONING DEVICE

摘要

A blanket tensioning device for an image transfer medium (ITM) cylinder includes two elongated blanket holders. A long dimension of each blanket holder is substantially parallel to a long dimension of the other. At least a part of at least one of the blanket holders is moveable toward or away from the other blanket holder. The device includes at least one spring that, is longitudinally arranged with respect to the long dimension and a transmission for converting a force that is exerted by the spring to a transverse force that is applied to the moveable part. When the device is installed on the cylinder with the long dimension being oriented substantially parallel to an axis of the cylinder, and when a blanket is wrapped around the cylinder with each of opposite ends of the blanket being held by each of the blanket holders substantially parallel to the cylinder axis, the applied transverse force tensions the blanket.

1. A blanket tensioning device for an image transfer medium (IT cylinder, the device comprising:
two elongated blanket holders, a long dimension of each blanket holder being substantially parallel to a long dimension of the other, at least a part of at least one of the blanket holders, being moveable toward or away from the other blanket holder; at least one spring that is longitudinally arranged with respect to the long dimension; and a transmission for converting a force that is exerted by the spring to a transverse force that is applied to the moveable part, such that when the device is installed on the cylinder with the long dimension being oriented substantially parallel to an axis of the cylinder, and when a blanket is wrapped around the cylinder with each of opposite ends of the blanket being held by each of the blanket holders substantially parallel to the cylinder axis, the applied transverse force tensions the blanket.
