Abstract
A riveting press wherein the female component of a composite button, knob or a like article of hardware is introduced between the jaws of first tongs below a sheet of textile material whose marked side faces upwardly, and wherein the male component of the article is introduced between the jaws of second tongs at a level above the sheet. The first tongs deposit the female component on a stationary anvil while the second tongs descend toward the upper side of the sheet to place the male component into the path of movement of a descending ram which causes a deformable part of the male component to penetrate through the sheet and to be deformed into permanent engagement with the female component by a centering stud which is provided on the anvil. The mechanism which moves the first tongs up and down derives motion from the mechanism which moves the second tongs and the ram.
