<p>An upper (10) and a lower (20) set of belts run on rolles (11, 12, 21, 22) forming a gap (30) between them. The rollers are rotated so that paper can be fed through the gap and on to an outlet surface (31). The control microswitch or microswitches (41) are placed so that the operating arms (40) pass between adjacent belts in the upper set (10). To provide space for these arms the lengths (20A) of the lower belts beneath the microswitches are deflected by a shaft (50). This shaft passes above the deflected lengths and beneath adjacent undeflected lengths. The position of the microswitch and the deflecting shaft can be adjusted.</p> |
