PERFORATING DEVICE Filed May 22, 1936 e e e fig. 5.

' m render them more permeable to liquids or gases or light and also more able of drying or to be freed of certain contents by the application of pressure, or by evaporation, or by heating, in short to prepare them for any kind of treatmeat whatsoever affecting their interior parts.

Sheets or films thus perforated can in certain.

cases thereby acquire the qualities of fabric's or plaits such as elasticity, softness, pliability, soaking ability, and others.

My new device has for its object to produce perforations for the said purposes in a most efficient way withoutany waste of material and allowing of arranging the single perforations as closely spaced apart as is preferable for special purposes. It ma be broadly stated that usually it serves the purpose of better opening up a sheet of whatever material to a certain treatment the nearer the perforations are located to one an other. A further object of ni y invention is to make the perforations at a g eat speed and to reduce the power needed.

With these objects in view, I provide a device with a plurality of needle-like pins operated to be oscillated in a vertical but simultaneously also in a parallel direction to the sheet, which itself is moved at a certain speed along and in front of the said tools. Instead of being moved vertically the pins'can also be moved at a certain angle to the sheet. Further, these pins can form 4.0 a single group or a plurality of groups arranged side by side or behind one another, or also in staggered positions and they can be operated so as to move simultaneously, or they can be timed differently. For supporting the sheet to be perforated I use a carrier which is itself of an open structure in the sense to let the pins enter freely when the penetrate the sheet farther than its thickness. Such a carrier for example may be a drum the surface of which consists Q0 of felt, or of a brush, or. of other materials which likewise can support the sheet against the action of the pinswithout offering the said pins any re sistance against penetrating. It may be of advantage to arrange between the sheet and the w pins members for holding the sheet free from the pins. the said members being either stationary or operated to move as the case may be'or also of a resilient'nature and in any case possessing slots for letting pass the pins towards and from the sheet. Finally, I use: pins which in planes rec- 5 tangular to the axis have a profile diflering from a circle being polygonal while the projecting corners of the polygon are connected by level or convex surfaces, whilst in the direction of the axis the surfaces may arch concavely. It may be of advantage to perforate the sheets while still being treated 'as they may possess in that case a greater elasticity or permeability. This may also simplify the kind of movements of the pins, for example when the sheet is in a moist condition it may suffice to move the pins straight in the direction'pf their own axis only.

In the drawing in which I have shown schematically two embodiments of my invention and of the tools employed therein,

Figs. 1 and 2 are views at right angle to each other of one embodiment;

Fig. 3 is a sectional view of another embodimerit of my invention, all parts not necessary for the understanding of the invention being omitted 2 and only the tools in their working position in relation to the sheet under treatment and the support of the latter being shown.

Figs. 4 and 5 show two different forms of tools with the profiles of their cross-sections.

In Figs. 1 and 2 the sheet a to be perforated is supported by an endless yielding member, e. g. felt-band 0 upon two rolls b which band is driven in the direction of the arrow. The pins d are arranged and held in groups by members e which 35 form the bottom ends of vertically suspended excentric rods each two of them being united by one of the said members e. The excentric f and the rolls b are supposed to rotate under the driving action of the main shaft of the device 4 here not shown thus moving the pins up and down and simultaneously transporting the sheet upon felt c by the transporting rolls. The totality of pins is divided in groups in lateral direction as well as in the direction of the movement of 45 the sheet, and their movements are differently timed, in order to allow the sheet a to move with ayconstant but high speed as is necessary with many materials and to balance the oscillating movement of the pins and their driving members. In the direction of the arrows 9 further excentric rods not shown and linked to the vertical ones give the latter a simultaneous oscillating movement in the horizontal direction. Their movements are timed so as to move the single group of pins in the same direction in which the sheet moves whilst the pins do penetrate the sheet but moving them in the opposite direction whilst the pins are lifted to clear the sheet.

In Fig. 3 the sheet a is supported by a roll the by them. By a selection the aforesaid angle a for' the direction of the pins and by the use of the plate m the working speed can be considerably increased.

Fig. 4 shows one preferred form of a pin d possessing a round shaft with a pointed end portion of triangular profile. The surfaces between the three edges are level and should not project over the direct connecting line between two edges in order to lessen friction when penetrating the substanceof the sheet. In the direction of the axis of the pin the edges may be arched outwardiy.

In Fig. 5 the point has a profile with four edges whilst the surfaces between these edges recede somewhat for further diminution of possible friction. In the direction of -the axis of the pin these edges run straight.

towards and away from the material to be periorated, a movable endless member carrying a brush both for supporting the material while being perforated and feeding the same.

2. In a perforating apparatus, in combination with pointed pins and means for moving the same towards and away from the material to be perforated, means for imparting to said pins an oscillating movement at an angle to the material to be perforated, and an elastic support both for supporting the material while being perforated and feeding the same.

3. In a perforating apparatus, a series of pointed pins adapted to be moved towards and away from the material to be perforated and of angular cross-section forming edges, the latter being arched in the direction of the axes of the pins.

4. In a perforating apparatus, in combination a pivoted two-arm lever, pointed pins carried by one arm of said lever, means engaging the other armof said lever for oscillating the lever,to move the said pins towards and away from the material to be perforated, a link for guiding said lever during its oscillations, and a yielding support both for supporting the material while being perforated and feeding the same.
