Definitions

  • This invention relates to a folding machine for folding sheet material in concertina fashion.
  • the present machine is intended to enable sheet material such as paper to be folded in concertina fashion whilst being responsive to different kinds and thicknesses of paper sheets by utilising the capabilities of electric microprocessors.
  • a folding machine for folding sheet material in concertina fashion, the machine comprising means to feed the material along a path towards a folding station, characterised in that a roller arrangement at said folding station includes first and second pairs of rollers having respective endless bands running around them, a third pair of rollers, a working run of each endless band being adjacent and substantially tangential to a respective one of said third pair of rollers, and a further roller, which is 'driven and is shiftable between a first position, where it can direct the sheet material at the start of a working cycle to between one of said endless bands and the adjacent one of said third pair of rollers, and a second position in which it remains during the remainder of the folding cycle to carry and move the stack of material being folded, and there being detecting means to detect the leading edges of the sheet material as folding progresses to cause reversal of drive of said roller arrangement to produce the folds.
  • a horizontal table TA is provided for feeding longitudinal sheets FO ( Figure 4) of material such as paper to be concertina folded to an inlet location and a feed means is provided in the form of a unidirectionally driving inlet roller RM 1 co-operating with associated idler rollers (or balls) RF 1 and RF 2 , these rollers serving to feed the sheets to an entry path or track CE.
  • NA 1 and NA 2 are sets of strongly tensioned endless bands extending around driving rollers RM 2 and RM 3 and around idler rollers RF 2 and RF 3 respectively, these bands being arranged at the folding station according to a specular symmetry about the plane.of the intended direction of feed of the sheet material along the inlet path CE.
  • Respective working runs of the bands NA 1 and N A 2 are arranged tangentially with respect to idler rollers RF 4 and RF 5 , these rollers RF 4 and RF 5 having respective tapered portions PE 1 and PE2 and toroidal guide grooves SC 1 and SC2 to accommodate endless belts CN wound around a pair of lower rollers RM 4 and RF 6 .
  • the roller RM 4 is driven and its direction of rotation can be reversed and the roller RF 6 is an idler roller. Accordingly, the rollers RM 2 and RM 3 drive respectively the rollers RF 4 and RF 5 Via the bands NA 1 and NA 2 .
  • Another roller RO is arranged to be driven in a direction which depends on the direction of rotation of the driving rollers RM 2 , RM 3 and RM 4 and is shiftable in said plane from an upper position (Figure 1) at the beginning of the operating cycle in order to direct the sheet material towards the band NA 2 and a lower position, which is achieved after the beginning of the cycle, whilst continuing to rotate in the same direction as the roller RM 4 , in order not to hinder the formation of folds in the sheet material ( Figures 2 and 3).
  • Detecting means in the form of photoelectric cells CF 1 and CF 2 control the directions of rotation of the driving rollers RM 2 , RM 3 and RM 4 .
  • a photoelectric cell CF 3 is located adjacent to the entry path CE.
  • the driving roller RM 1 feeds the sheet FO towards the entry path CE until the sheet drops to the folding station to meet the rotating roller RO (which is in its upper position) so that the sheet is directed between the lower, working run of the band NA 2 and the roller RF 5 and consequently the sheet is positively carried towards the photoelectric cell CF 1 .
  • a servocontrol causes the direction of rotation of the driving rollers RM 3 and RM 4 to be reversed, whilst the driving roller RM 1 continues to rotate always in the same initial direction. As can be seen from Figure 2, this has the effect of drawing the sheet material such as paper to form a loop to provide a first fold therein.
  • the photoelectric cell CF 3 mounted in the entry path CE is instrumental in initiating the rotation of the rollers RM 2 , RM 3 , RM 4 and RO.
  • the present folding machine does not have stationary channels between which the pack of folded sheet material can slide during the folding operation as with a known machine; on the contrary, the "channels" are movable and consist of the belts CN and bands NA 1 , NA 2 which accompany the material during the reciprocating movement whereby movement of the material is not hindered thereby inhibiting consequent jamming of the machine.
  • roller RO performs the important job of orientating correctly the leading border of the paper, so as to orientate the latter according to the required inlet or feed direction, without sensing the initial pre-bending that the paper may present in the opposite direction.
