ROBERT WILISCH Sr. in SCHNEEBERG. Smoothing machine for endless paper.

Patented in the German Empire on August 19, 1877.

The invention aims to machine smoothing endless paper on strips of wood, Leather, rubber or hard rubber, paper mache, steel, agate stones, glass and so on, depending on the fabrics to be smoothed.

Fig. Ι is a front view of the machine, Fig. 2 is a side view of the same, - Fig. 3a and 3 b the so-called. Pliers, Fig. 4 the smoothing sheet.

The actual smoothing apparatus rests on a secure frame A, while the drive of the same comes from the shaft a with pulleys b , which is mounted on a bearing block B on the side. A flywheel c sitting on the same shaft α moves the tongs e by means of the push rod d , which by its two parts, which resemble the jaws of a filing block, ^ ₁ and <? _{2 is} able to securely grasp the smoothing stone, which has to take care of the actual smoothing, in a reciprocating motion.

The partly steel pliers e are inserted by means of a cylindrical pin e _s (Fig. 3) into a longer rod / which has its fulcrum on an elastic post suitably attached above the machine. The purpose of the elasticity of the post used here is to exert a certain pressure, which is as uniform as possible, of the smoothing steel clamped in the pliers against the paper lying over the web g. The cylindrical pin e _s the forceps allows in an easy manner, rotation of the forceps 90 ^0, hence ψα smoothing with the broad both narrow than the side of the steel.

You only need to remove the Charnierstück h from the upper hole Z ₁ and insert it into the lower z ₂ , respectively. bring the bolt k into the upper hole Z ₁ (Fig. 3).

The track g, which, as mentioned, can be made of wood or rubber, leather, paper mache, steel, etc., is attached to the frame A (FIG. 2) A frame m, screwed to the rear of the frame A , carries the supply roller u, on which the paper to be smoothed is stored.A part of the latter is unwound from time to time by means of a crank It _{1 and then hangs in a long fold to the floor} down, leads from there through the rollers ₂ and ₃ to the table / and over the web g under the roller 0 and through the pair of pulling rollers P ₁ p ” to the take-up roller p.

On the side of the axis of the roller p there is a ratchet wheel r, which is fixed by means of the ratchet teeth r _± , r ₃ and the lever J ₁ , 'of the pull rod J ₂ , the levers J ₃ and J ₄ and the Push rod t experiences a periodic continued rotation from a crank 4 seated on the drive axis α. The size of the latter, measured on the circumference of the draw roller P ₁ , is taken to be equal to the width of the paper strip to be smoothed when the smoothing steel moves.

The slot crank of the flywheel C and the just mentioned crank 4 are offset from one another by 180 °.

The paper lies still as long as the smoothing steel brushes over it; the forward movement of the roller pi , which takes place in the meantime, causes a certain tension of the paper lying between it and the web g in such a way that thereby a wooden roller O, which leans against two laterally arranged strips U (Fig. 2), by a certain amount Amount is raised. Immediately after the smoothing steel, the stroke of which is greater than the width of the paper, has left the latter, the weight of the above-mentioned wooden roller O causes it to sink down, and therefore also to advance the paper, so that the receding smoothing steel creates a new strip for smoothing finds.

Also to be mentioned are the chalk containers υ which are adjustably attached to the upper part of the frame m. The purpose of these is to hold pieces of chalk against the outermost edges of the paper in such a way that it will chalk itself on the supply roller u as it rotates (which often appears necessary when smoothing colored paper).

The advantages of this machine are as follows:

1. As a result of the regular, automatic of the machine-induced advancement of the paper never runs empty of the webs So the risk of burning the train, respectively. the cracking of the stones, avoided.

2. Experience has shown that the machine offers great advantages also when smoothing short, format

Cut paper, such as colored paper, cardboard, etc. No less useful is the possibility, brought about by the rotatability of the pliers e , to smooth transversely or lengthways with the steel as desired.

3. The efficiency of the machine, which the latter can be achieved through appropriate use of the machine existing adjustment devices are always set to their most advantageous speed is at least twice as large as that of an ordinary smoothing machine.

4. The machine requires very little operation. A person can do 10-12 to supervise.

The device of the machine, that it smooths paper without end, can be used by any existing one Adjust the trowel system.
