FIELD: machines for elements embossing.
SUBSTANCE: inventions group relates to machines for embossing elements in the form of sheets. The tape unwinding device for the embossing machine is configured to accumulate the tape in a pre-unwound form between the embossing roll and the plate press of the embossing machine. The tape unwinding device contains a central drum made with the possibility of rotation at a variable feed rate and is fixedly connected during rotation with the axis of the tape unwinding device. The tape unwinding device comprises a satellite roller having an axis parallel to the axis of the central drum. The satellite roller is designed to rotate around the central drum. The tape unwinding device comprises a planetary drive device for moving the satellite roller around the central drum depending on the difference in the rotation speeds of the central drum and the outer rim of the planetary drive device.
EFFECT: invention improves placement accuracy and reduces tape consumption.
