1-19. (canceled)
A launcher of paper products for packaging stations of paper product converting lines, comprising a frame where at least two modules for launching the products are arranged, each module of said at least two modules comprising at least one launch channel, so that the launcher comprises at least two launch channels, on which the products to be launched are arranged, and wherein each launch channel of said at least two launch channels has opposite movable surfaces, with at least one of said opposite movable surfaces being motorized, arranged in contact with opposite sides of a respective product housed in the launch channel, to drag the product in a launch direction,
- wherein the two opposite movable surfaces are arranged below and above, respectively to provide a lower movable surface and an upper movable surface, a space that can be occupied by the product in a respective one of said at least one launch channel, so as to drag the product by acting on the lower side and the upper side thereof,
- wherein a device is associated with at least one module of said at least two modules for adjusting a distance between the lower movable surface and the upper movable surface of a respective one of the two opposite movable surfaces of a respective one of said at least one launch channel including at least a first adjusting device being associated with a first launch module for adjusting distance between the respective opposite movable surfaces of the respective at least one launch channel, and a second adjusting device being associated with a second launch module for adjusting distance between the respective opposite movable surfaces of the respective at least one launch channel, so that distances between the movable surfaces of the at least one launch channel of the first launch module are adjustable independently of distances between the movable surfaces of the at least one launch channel of the second launch module, so that the at least two launch modules can house products of different heights.
