摘要:
A snap fastener comprises a female part to be clamped on a first flap, for example of the fabric material, and a male part, to be clamped on another flap of the fabric material, in which the female part comprises an active element and a clamping element, the active element and clamping element having different surface finishings. Moreover, through the exposed to view part of the active female element are provided a plurality of openings, having different configurations, therethrough it is possible to see the top surface of the clamping element. With respect to prior snap fasteners, the inventive snap fastener has the advantage of providing chromatic effects, which can be easily obtained at the female part of the pushbutton.

A pressure button, of the type comprising a male portion and a female portion, to be applied on flaps to be connected, the female portion comprising a fixing element for fixing an active female element, the latter including a plurality of resilient tabs which are mutually arranged with a ring arrangement about a housing recess for housing a projecting part of the male portion. The active female element of the button comprises an annular body to which a clamp element including a plurality of points projecting outside of the active female element is affixed. In particular, the assembling means for assembling the female portion are so arranged as to operate at a separated and moved away position from the resilient tabs, thereby the assembling of the female portion, for applying the latter on a respective material flap, can be performed without modifying the mutual shape and/or arrangement of the resilient tabs, thereby preserving the rated clamping pressure of the button.

摘要:
A machine for automatically applying snap fasteners on a support, such as a fabric, comprises a sensor for sensing the instantaneous value of the riveting pressure applied to the machine punch elements. With respect to prior machines for automatically applying snap fasteners, the machine according to the invention provides the advantage that the snap fastener can be applied to a fabric with a proper riveting pressure, so as to prevent both excessive pressures, which could damage the fabric, and insufficient pressures, which could not provide a proper connection of the snap fastener on the support, from being generated.
