at a comparatively slower speed of 1100 feet per minute replaces the first series of lower high speed belts 14 just prior to entering the area where the sheet 30 will be folded the series of lower low speed belts 28 is spaced a greater distance from the series of upper high speed belts 12 than was the series of lower high speed belts 14 the lower low speed belts 28 traverse a series of idler pulleys 32 mounted on a freely rotating shaft 34 and a set of drive pulleys 36 mounted on a drive shaft 38 a reduction gear 40 also mounted on the shaft 38 is driven by a gear 42 mounted on the shaft 18 the set of lower low speed belts 28 may also be driven by a variable speed independent drive as is well known in the art the sheets 30 are caused to decelerate in order that they can be stopped without damage and folded by means of snubber wheels 44 freely rotatable about axles 46 attached to one end of a snubber cam 48 the snubber cam 48 in turn is mounted to a shaft 50 the shaft 50 has a timing pulley 52 mounted at one end fig2 a which is driven directly from the printing press by means of a timing belt 54 the ends.
