Machine for applying articles of hardware to tensioned textile materials

摘要

A riveting press wherein a vertically movable downwardly yieldable platform supports a selected portion of a textile workpiece between a passive lower tool and a vertically rciprocable upper tool. The upper tool is surrounded by a set of two or more radially outwardly movable and vertically reciprocable grippers having serrated undersides which are moved downwardly and into engagement with the upper side of the workpiece on the platform before the upper tool descends to affix a first component of an article of hardware to the workpiece simultaneously with the application of a second component of such article to the first component and to the workpiece. One such component is supported by the lower tool and the other component is releasably held in sockets of the grippers below the upper tool. The shaft for the upper tool carries a cam which spreads the grippers apart while the grippers engage the workpiece so that the latter is stretched during the interval of application of an article of hardware thereto whereby the portion of the workpiece on the platform is devoid of wrinkles and/or other irregularities in the area around the applied article of hardware.
