Launcher of paper products

A launcher of paper products for packaging stations of paper product converting lines, comprising a frame where at least two launch channels are provided, 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, at least one of said opposite movable surfaces is motorized, arranged in contact with opposite sides of a respective one of said products housed in the channel, to drag the respective one of said products in the launch direction, wherein two of said opposite movable surfaces are arranged below and above the space to provide an upper side and a lower side that can be occupied by the respective one of the products in the channel, so as to drag the respective one of the products by acting on the lower side and the upper side, and wherein at least an apparatus is provided for kinematically connecting the movable surfaces which are motorized, at least one kinematic disconnection/connection device being provided for kinematically disconnecting/connecting at least one of said movable surfaces from/to the at least one kinematic connection apparatus, that can be operated on command,

• wherein said at least one launch channel of said at least two launch channels is adapted to be connected or not connected to said kinematic connection apparatus based on whether said disconnection/connection device is adapted to act on the at least one launch channel for connecting/disconnecting, so that based on the disconnection/connection device:
• said at least one launch channel is adapted to act together with at least a further launch channel connected to the kinematic connection apparatus, or
• said at least one launch channel is not adapted to act together with at least a further launch channel connected to the kinematic connection apparatus,
• so that in said launcher it is possible to have at a same time at least a launch channel adapted to launch when connected to the kinematic connection apparatus, and at least a launch channel adapted not to launch when disconnected from the kinematic connection apparatus.
