Abstract (en)
[origin: US4463771A] The device provides an arrangement of the input and output ends of the machine which is of light and cheap construction, smaller in size and allows an adaptation of the machine in accordance with the width of the product to be treated. The device comprises, for each end of the machine, at least one rigid closing shutter carried by one of the frames of the machine. Guiding devices carried by this frame ensure a displacement of the or each shutter in a direction roughly perpendicular to the plane of the sheet passing through the machine. Devices for shifting the or each shutter are provided. The or each shutter cooperates by its free edge with the other frame of the machine so as to close in a substantially sealed manner the input or output end of the machine.
