A substrate in the form of a continuous sheet is fed towards a belt conveyor and is lied out on the conveyor itself. By means of the belt conveyor, the substrate is moved along a feed direction, while a printing unit operating above the belt conveyor realizes a print pattern on the substrate. The printed substrate is withdrawn by a traction unit operating downstream of the belt conveyor. In a section of its longitudinal extension between the belt conveyor and the traction unit, the substrate is subjected to a braking action to retain the substrate in contrast to traction actions induced on the same by the traction unit. A drying group operates on the substrate in the area affected by the braking action, with a combined action of radiation and ventilation.

In an example, a load stop may comprise a stop paddle, a paddle link, a swingarm engaged with a motive element, and a cam gear to engage the swingarm with the paddle link. The paddle link may move the stop paddle from a locked position, to a gathering position, and to a stowed position. The swingarm may transfer the motion of the motive element to the cam gear such that the cam gear is to move in a first direction, the cam gear to drive the paddle link to move the stop paddle from the locked position, to the gathering position, and to the stowed position when the motive element moves in a first drive direction, and the swingarm moves the cam gear in the first direction.

A rotation velocity adjusting module includes a fixed axle, a rotating component and a rotation velocity adjusting mechanism. The rotating component is pivoted to the fixed axle. The rotation velocity adjusting mechanism includes a driven component, a driving component and a contact component. The driven component is rotatably connected to the rotating component. The driving component and the contact component are disposed on the driven component. When a rotation velocity of the rotating component reaches a threshold value, the driving component drives the driven component to rotate by the change of centrifugal force, so as to switch states of the contact component.
