• the selector pins 102a, 102b and 102c at this stage pass through an unimpeded portion 93a of the guide apertures 92a, 92b and 92c of the second punch plate, and thus the second punch plate is not acted upon by the selector pins as the operating member advances.
• the locking pin 112 passes through a transverse slot-like portion 96a of the control aperture 96. Since the locking pin is prevented from moving in the longitudinal direction by engagement within the transverse guide slot 66 of the base plate, the second punch plate is prevented from moving from its retracted position. Conversely, the locking pin 112 passes through an unrestricted portion 86a of the control aperture 86, permitted the first punch plate to move freely, (see Figure 8).
• a stack of material to be provided in its edge margin with a first plurality of apertures may be placed in the material slot in engagement with adjustable support members, described in detail hereinafter, and with the control member in its first position, the operating member 70 may be caused to advance to cause the punch members of the first punch plate to move into the slot 38 and through the stack of material therein.

• the selector pins engage inclined cam surfaces 84 of said guide apertures 82 to move the selector member into a second position.
• the locking pin 112 is carried across the portion 86b of the control aperture 86 thereof, whilst the selector pins 102 are carried into engagement with transverse slot-like portions 93b of the guide apertures 92a, 92b and 92c of the second punch plate 90, (see Figure 10).
• the second punch plate 90 may be moved longitudinally by the operating member whilst the first punch plate is retained in its advanced position.

• This operation may be repeated as desired, and at an appropriate time, with the assembly in its retracted position, the selector member may be moved to its first position.
• the operating member When it is desired to actuate the first punch plate, with the operating member in an advanced position, the operating member may be moved from its second position to towards its first position into an intermediate position, said intermediate position being determined by engagement of the locking pin 112 with a side wall 96c of the control aperture 96, in which position the selector pins 102 are located once more within the transverse slot-like sections 83a of the apertures 82, Figure 12.
• both the first and second punch plates are simultaneously retracted.
