  • Tool
    Patent number: 5709122
    Abstract: A tool for manufacturing signs wherein selective sign display elements are retained in a base profile section by folded engagement of opposite end portions of the base section. The tool includes members for cutting the base section, compression members for deforming the base section to secure the sign elements from disengagement with the base section and a punch for providing an aperture in the base section. The tool further includes a guide surface for positionally aligning the base section and gauge blocks for displacing the guide surface generally perpendicular to a longitudinal axis of the base section to accommodate respective base sections having different width dimensions. A stop member restricts movement of the sign display elements when cutting the base section.
