  • the rotation of the first rotation axle 180 by the first motor 171 causes a synchronous movement of the first carriage 142 and the second carriage 152 in the transverse direction T on respectively the first guide 141 and the second guide 151 via respectively the first belt and pulley system 144, 144' and the second belt and pulley system 154, 154'
  • the rotation of the second rotation axle 185 by the second motor 174 causes a synchronous movement of the third carriage 146 and the fourth carriage 156 in the transverse direction T on respectively the third guide 145 and the fourth guide 155 via respectively the third belt and pulley system 148, 148' and the fourth belt and pulley system 158, 158'.
  • the configuration of the drive system for the first folding blade 130 and the second folding blade 135 described above, and its positioning in the device 100 above the conveyor system 110 and the folding blades 130, 135 and along the periphery of the device 100, i.e. along the first longitudinal side 101, the second longitudinal side 102, the first transverse side 103 and the second transverse side 104, is beneficial to have an easy access to the drive system and also to the folding blades 130, 135 for maintenance and repairs.
  • the combination of the folding blades 130, 135 and the drive system for the folding blades 130, 135 arranged on the first beam 140 and the second beam 150 may be integrated into the device 100. Said combination, may however also be provided as a separate extension module 200, such as for example shown as a first embodiment in Figures 3-5 and a second embodiment in Figure 6 and 7 , to be installed on an existing device for longitudinally folding a textile item 900, which is not yet provided with the functionality of folding blades 130, 135 for folding the textile item 900 over folding template parts of said device.
  • the drive system for the folding template parts 120, 125 is arranged on the third beam 160, as shown in more detail in Figure 8 and 9 . Therefore, the third beam 160 is provided at the bottom with a fifth guide, track or rail 161 and a sixth guide, track or trail 165, which guides 161, 165 extend along the transverse direction T.
  • the fifth guide 161 and the sixth guide 165 may be two separate guides, but may also be arranged in extension of each other and connected such that they form a single guide.
  • On the fifth guide 161 and the sixth guide 165 there is respectively arranged a fifth carriage 162 and a sixth carriage 166, which carriages 162, 166 are moveable in the transverse direction T on the corresponding guides 161, 165.
  • the first folding template part 120 is connected at a first end 121 to the fifth carriage 162, and the second folding template part 125 is connected at a first end 126 to the sixth carriage 166, such that the folding template parts 120, 125 can be moved in the transverse direction T for setting the longitudinal fold position 901, 902 along the textile item 900 by moving the corresponding carriages 162, 166 in the transverse direction T on the corresponding guides 161, 165.
  • the drive system for the folding template parts 120, 125 further comprises a single third motor 177, preferably an electric servo motor 177, which drives the movement of both the fifth carriage 162 and the sixth carriage 166 via a fifth belt and pulley system comprising a fifth drive belt 164 and fifth pulleys 164'.
  • An upper part of the fifth drive belt 164 is connected to the fifth carriage 162, and a bottom part of the fifth drive belt 164 is connected to the sixth carriage 166.
  • the third motor 177 when active, causes via the fifth belt and pulley system 164, 164' a symmetric movement of the first folding template part 120 and the second folding template part 125 with respect to each other in opposite directions along the transverse direction T on the corresponding guides 161, 165.
