Abstract
The side walls (6, 7) adjacent a vertically reciprocable platform (3) are moved towards each other to compress compressible products (1), such as kitchen paper towels, toliet paper and the like, for introducing them into a plastic bab (B) upon vertical movement of the platform (3). The side walls are coupled through cam follower rollers (6b, 7b) to inclined guide tracks on guide track elements (9, 10), and slidably coupled to move with the platform on a guide rod (8). The angle of inclination of the guide tracks is adjustable, as well as the separation of the guide tracks from each other, so that the degree of compression, as well as the size of the compressed package, can be readily controlled.
