Device and a method for clampingly positioning a heat transfer sheet around a substrate

A device for clampingly holding against a substrate a flexible and stretchable clamping sheet and a heat transfer sheet, wherein the clamping sheet has a width and has a length, said length being measured between longitudinal ends of the clamping sheet, said device comprising coupling means at the longitudinal ends of the clamping sheet and a substrate holder with a positioning-axis for holding the substrate, such that a longitudinal axis of the substrate substantially coincides with the positioning axis of the substrate holder, and wherein the device further comprises:

• a table for carrying the clamping sheet and the heat transfer sheet in a first position at a distance from the substrate holder;
• and
• a translation device for moving the table and the substrate holder mutually towards each other, such that the translation is performed substantially perpendicular to a surface of the table;
• and wherein:
• the substrate holder is coupled substantially rigidly to a main frame of the device;
• the translation device is coupled movably with respect to the main frame of the device;
• said translation device comprising a first sub frame comprising a rotatable camshaft, comprising a first cam of which runs over a first cam support rigidly coupled to the main frame and a second cam which runs over a second cam support forming part of a second sub frame;
• and
• said second sub frame comprising catch means for holding the clamping sheet and the heat transfer sheet;
• and wherein
• when the rotatable camshaft rotates over a first rotation angle the first cam moves the two sub frames in the direction of the substrate;
• and wherein
• in a subsequent rotation of the rotatable camshaft through a second rotation angle the second cam moves the second sub frame such that the second sub frame is at least partly on both sides of the substrate.
