Abstract
The present invention relates to an anchoring device for the covering (9) of a fabric boom on its associated support, which provides for extraction of the totality of the piece of fabric (9), including its extremities. This extraction, accomplished by means of a roller extractor, is made possible by providing anchor studs (14) having an underlying recess and extending from the upper surface of the support (1-3), through the use of articulated lever-shaped connecting grips (5) on support (1-3) having an arm that exerts pressure on appendages (15) of the piece of fabric (9) without interfering with the heads of anchor studs (14), and lateral shoulders (13) on support (1-3) configured in such a way that they define between them a determinate space from which neither anchor studs (14) nor connecting grips (5) emerge.
