Title:
FOIL TRANSFER DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/112888
Kind Code:
A1
Abstract:
Provided is a foil transfer device which transfers foil to a long medium and is capable of suppressing variations in tension of the medium when the foil is transferred. In the foil transfer device 1, foil transfer rollers 29 and 30, constituting a transfer roller pair 7 for pressing a foil transfer sheet 3 against a medium 2 to which an adhesive has been applied to transfer the foil to the medium 2, are driven rollers that rotate following the medium 2 conveyed by a medium conveying mechanism 6. The motor of a medium winding mechanism 34, which winds the medium 2 to which the foil has been transferred, is driven regardless of whether the medium conveying mechanism 6 is conveying the medium when the foil is transferred to the medium 2. In the medium winding mechanism 34, a torque limiter disposed in the power transmission path from the motor to a roll-shaped medium 33 causes the motor to idle with respect to the roll-shaped medium 33 when the torque transmitted from the motor to the roll-shaped medium 33 exceeds a predetermined value.
