This arrangement allows the advance movement of the lugs 100, 101 and 102 downstream in the active position and their return upstream in the inactive position.
  • the cleats are mounted sliding axially along fluted shafts such as 195, by means of complementary fluted sleeves 196 cooperating with the shafts 195.
  • With the sleeve 196 is rigidly associated a grooved roller 197 also mounted on and around the splined shaft 195.
  • a longitudinal projection 198 forming a rail cooperates with the groove of the roller 197.
  • This longitudinal projection 198 forming a rail is joined integrally and kinematically to the spar of one of the spars 30.
  • the fluted shafts 195 are carried so as to be pivoting. They are movable with transverse (relative to their axis) and longitudinal (relative to the machine) sliding.
  • the projections forming the rails cause the axial sliding of the sleeves 196 and therefore the transverse adjustment of the cleats.

  • crankpin 147 crankpin 147
  • connecting rod 148 lever 149
  • connecting rod 150 connecting rod 151
  • connecting rod 151 connecting rod 151
  • connecting rod 151 connecting rod 151
  • axis 99 is carried by bearings 154.
  • the machine 1 comprises, instead of the plate 40 two bars 155 extending horizontally and longitudinally carried by two arms 156 (or pairs of arms) articulated around horizontal and longitudinal axes 157 in the same vertical plane and close to one another, the assembly 155, 156, 157 forming a sort of axially extended clamp opening and closing.
  • the axes 157 are carried by a carriage 158 carried and mounted vertically sliding by means of two vertical threaded columns 159 'cooperating with threads of the carriage 158, placed in the same longitudinal vertical plane.
  • These two threaded columns 159 are themselves carried, at their lower parts by the corresponding spar 30 and, at their upper parts by a longitudinal and upper horizontal spacer 160 maintained at a fixed spacing by means of rods or the like 161, horizontal and transverse of another spacer 162 horizontal, longitudinal, upper, coplanar with the spacer 160 but on the opposite lateral side of the machine, which spacer 162 supports two vertical columns 163 placed opposite the threaded columns 159 but on the other lateral side of the machine.
  • the columns 163 are, in turn, carried by one or more carriages 164, driven, rolling in the horizontal transverse direction, sliding and by means of rollers 165 on horizontal and transverse slides 166 fixedly carried by the frame 18.
  • Two other threaded columns 167 near the columns 163 extend vertically carried between and by the carriage (s) 164 and the spacer 162. Toothed gears 168 wedged at the projecting upper ends of the threaded columns 159 and 167, connected by a chain without end 169 or any equivalent means associated with a motor 170, to which we will return later, allows synchronous drive and in the same direction of the threaded columns 159 and 167.
  • On the threaded columns 167 is mounted a carriage 171 by threads suitable, this carriage 171 being placed horizontally in the same plane but opposite the carriage 158. the carriage 171 supports the counterpart means 42.
  • the two carriages 158, 171 are therefore moved in synchronism and are horizontally and transversely at a constant distance l 'one from the other.
  • one or more lower transverse horizontal rods 172 are provided to maintain this distance.
  • Means such as jacks have the function of opening and closing the clamp 155, 156, 157.
  • the counterpart means 42 are, in this embodiment constituted by a single line of jacks 45 arranged in a horizontal plane intended to come to be applied to the bottom of the body 2, from the inside, in its median zone, opposite and against the two arms 156 brought close to each other, the corresponding clamp being closed.
  • the change in format of the body 2 is taken into account for the jacks 45, only in the event of a change in horizontal length, the number of active jacks being adapted accordingly.
  • the structure described above with the rods 161 and 172 has the consequence that the stroke of the jacks 45 is constant regardless of the body format 2 (in the transverse direction).
  • the spar 56 of the machine is, in this embodiment, carried by an upper horizontal frame 173 mounted to slide vertically by means of four vertical threaded columns 174 of fixed axes carried by the frame 18 of the machine.
  • These threaded columns 174 are arranged, in particular connected by sprockets, chains or the like to rotate in synchronism in the same direction.
  • the threaded columns 174 are driven by the same motor 170 as the threaded columns 159 and 167, with, however, a reduction gear so that the sliding stroke of the frame 173 is twice that of the carriages 158 and 171 or that the stroke of the carriages 158 and 171 is half that of the frame 173.
  • the motor 170 can be of vertical axis and housed at the lower part of the machine, fixed as a whole on its lateral edge and driving the threaded columns 159 and 167 via a toothed wheel 175 double that of 176 driving the threaded columns 174.
  • the toothed wheel 175 has a vertical fixed axis carried by the frame 18.
  • the side members 30 are mounted to slide horizontally and transversely, in opposite directions and in synchronism by means of threaded rods 32 and a motor 1 " 78 and support the slides 90.
  • the displacements of the side members 30, therefore of the cleats 100, 101, 102, in transverse direction is independent but combined with the relative displacement of the jacks 45, hence the existence of the carriage 171.
  • the columns not only do the threaded columns 159 and 167 rotate twice as fast as the threaded columns 174 but also the vertical axes of the threaded columns 159 and 167 are movable horizontally and transversely while the axes of the threaded columns 174 are fixed, hence the structure of frame 173 of larger dimensions than that of the threaded columns 159 and 167 in their different positions.
  • the clamp 155, 156, 157 occupies, in turn, a fixed transverse relative position relative to the corresponding spar 30 so as to be permanently in the same relative position relative to the bottom 4 of the body 2 regardless of its format .
  • the beam 68 is carried directly by four threaded columns 179 with vertical axes carried in the lower part by the frame 18.
  • the threaded columns 179 are driven from a gear motor 180 by a chain 181 and toothed pigs 182.
  • the arm 69 is driven by a geared motor 183 and a crank rod 184, instead of a jack.
  • the support plate 77 extends downstream beyond the gluing means 72, as far as the middle part of the ramps 73.
  • a single geared motor 185 carried by the frame of the machine, in a fixed position causes on the one hand, the endless belt 74 by means of a drum 186 of horizontal axis and, on the other hand by identical drums 187 of vertical axes, the endless side bands 78.
  • the moto- reduction gear 185 is associated with the drum 186 by a sliding angle box 188 on a keyed shaft 189 and with the drums 187 by sliding cardan drives 190.
  • rollers 191 are provided for lateral retention of the body at its upper part , of vertical axes carried by two longitudinal and horizontal supports themselves carried by transverse threaded rods 192 by bearings 193 carried by the beam 68.
