I l 7 I I ZEZQ Illllllllillllfiin in accordance with a further United States Patent 3,107,181 DEVICE F03 APPLYHNG PATCHES 0F GREASY ADHESIVES T0 RAZOR BLADE WRAPPERS Ulrich Bauder, Stuttgart, Germany, assignor to Firma Fr. Hesser Maschinenfahrik-Aktiengesellschaft, Stuttgait-Bad Cannstatt, Germany, a corporation of Ger- Filed Apr. 18, 1960, Ser. No. 23,049 Claims priority, application Germany Apr. 22, 1959 4 Claims. (Cl. 118-211) This invention relates to a device for applying patches of Vaseline or similar greasy adhesives to razor blade wrappers.
The device according to this invention is provided with a rotary feed drum which dips into a supply reservoir containing Vaseline or similar greasy adhesives and has one or more pistons sliding in radial holes opening at the peripheral face of the drum and so controlled by a fixed eccentric, for instance are eccentric disc that, during the rotation of the feed drum through the supply reservoir, adhesive enters the holes of the feeding drum and is forced out of the reservoir by the pistons and is transferred directly to a web of wrapper material passing over the drum.
To guarantee that the part of each hole freed by the corresponding piston is properly charged with adhesive, feature of the invention, a counter roller is provided within the reservoir and runs in contact with the feed drum so as to force the adhesive against the latter and press it into the holes.
This device, of very simple construction, insures that at all times substantially equal-sized patches of adhesive are applied to the razor blade wrapping material irrespective of the output rate to which the wrapping machine is set.
This invention is illustrated, by way of example, in the accompanying drawing, in which:
FIGURE 1 is a cross section through the device, and
FIGURE 2 is a horizontal cross section through the device of FIGURE 1.
A feed drum 3 is rotatably mounted in bearings of a housing 1, forming the lower part of an adhesive containing reservoir 2, so that this drum, which spans the width of the lower part 1, dips approximately half way into the reservoir. Radial holes 4 are provided in the periphery of the feed drum 3 and are spaced from one another, and a piston 5 is displaceably arranged in each of the radial holes.
The hub 6 of the feed drum 3 has an axial bore 7 into which projects a spigot 8 secured to the lower part 1 of the reservoir. This spigot 8 has at the end thereof an eccentric disc 2 the eccentric position of which in relation to the medial axis of the feed drum 3 can be adjusted in the plane containing the axis of the feed drum 3 and that of a diverting roller used to guide the wrapper web B. To allow for its adjustment, the eccentric disc 9 has a guide tenon seated in a transverse groove 22 in the spigot 8 and is fastened to the latter by a screw 23.
The pistons 5 are urged, under the action of embracing springs 21, against the eccentric disc 9. The pistons 5 are thereby controlled during the rotation of the drum 3 so that, during their passage through the reservoir, the pistons are first retracted into the holes 4 allowing the adhesive to enter the opened part of the holes 4, and then pushed out again, towards the reversing roller 10, by the pistons 5 during the other half turn. Since the Web B of wrapping material moves directly past the periphery of the feed drum 3, the blobs of adhesive issuing from the holes 4 are transferred to the web B in the form of patches T.
ice
If desired, the eccentric disc 9 can be so regulated that the pistons project somewhat beyond the periphery of the feed drum 3 in their outermost positions. As a consequence, the blobs of adhesive are separated completely from the feed drum 3 before coming into contact with the web B, and smearing of the web is thus precluded.
To promote the supply of adhesive to the holes 4 in the feed drum 3, a counter roller 11 may be rotatably mounted in the lower pant 51 of the reservoir 2 with the periphery of the roller 11 bearing against the feed drum '3, the roller -11 being driven in the opposite direction of that of the feed drum 3. The adhesive is delivered by the periphery of the counter roller 11, exactly as in the case of the feed drum 3, so that there is an adequate pressure above the line of contact of the two rollers to force the adhesive into the holes 4 of drum 3.
The counter roller 11 is not necessary in all cases but primarily only where particularly viscous adhesives have to be applied. In an embodiment of the device omitting the counter roller 11, the reservoir 2 is most advantageously disposed vertically above the feed drum 3 and the reversing roller 10 vertically therebeneath.
To insure that the adhesive in the reservoir 2 runs uninterruptedly downwards and contacts the peripheries of feed drum 3 and counter roller 11, a heating body 12, adjustable by means of a thermostat (not shown) is provided for the reservoir 2. By this means, the viscosity of the adhesive applied against the container wall may be modified so as to insure that the complete mass can slide downwards to the feed drum 3 and the counter roller 11.
The device can be driven through a gear 13 which may be driven, for instance by an eleotromotor, gear 13 meshing with a gear :14 connected to the reversing roller 10. A toothed wheel 15 secured to the hub 6 of the feed drum 3 engages the toothed wheel 14 and drives a toothed wheel 16 secured to the axis of counter roller 11. The gear ratios of the individual gear 14, 15 and 16 are selected so as to make the peripheral speeds of the reversing roller 10, the feed drum 3 and the counter roller 11 equal. This relationship is, however, not absolutely essential as between the feed drum 3 and the counter roller .11.
The residue of adhesive remm'ning on the end face of a piston 5 is drawn back into the associated hole 4 by the automatic retraction of the piston 5 into the drum 3, so that no agglomeration of adhesive can build up at the inlet of the reservoir 2, and there will be no consequent smearing of the feed drum.
At stripper 25, which is shown in FIGURE 1 and arranged at the outlet from the lower part 1 of the reservoir 2, is desirable inasmuch as it maintains the surface of the feed drum clean.
