<p>The lead-in guides (13) for the shuttering guide rails (9) comprise a metal support (16) insertible into length grooves (21) in coupling journals (8) and a plastic head (17) releasably secured to the support. The shutters have a box (1) which is sealed at both ends with caps (2). The winding shaft (3) for the shuttering (4) is mounted in these caps. Guide rails for the side edges of the shuttering are connected to the box. Coupling journals on the end caps extend into the guide rails in their length direction, forming a form-fit connection with these rails outside their guide regions. A lead-in guide for the guide rails is supported by the coupling journals between two guide sections (14, 15). The lead-in guides can be inserted into length grooves in the coupling journals, at right angles to the latter.</p> |
