ABSTRACT:
An apparatus and method for feeding single sheets of laminated thermographic print media are disclosed. The apparatus includes a traveling vacuum roller reciprocatable between pickup and discharge positions under suitable control so as to engage an end of the sheet near the pickup end and roll the sheet thereabout to a selected first angular position and then releasing the sheet end at such position. The vacuum roller continues to engage the sheet and applies a vacuum to engage the other end of the sheet so as to carry it to a second angular position and then releasing the sheet by releasing the vacuum as the roller approaches the discharge position. A wrapping roller engages the vacuum roller for directing the end of the rolled sheet towards the discharge after releasing it. A lift mechanism near the discharge position lifts the vacuum roller as it approaches the discharge.
