Definitions

  • the elongated, superposed webs are advanced between a notched, edge-beveled wheel and two beveled anvil surfaces so as to subject the webs to a pair of transversely aligned, intermittent compressive forces.
  • FIG. 1 is a fragmentary elevational view, partially in cross section, of apparatus incorporating teachings of this invention
  • FIG. 2 is an end elevational view of the apparatus of FIG. 1 such as would be seen essentially along the sight line 2-2 applied to FIG. 1;
  • FIG. 3 is an opposite end (or top) elevational view of the apparatus of FIG. 1, such as would be seen along the sight line 3-3 applied to FIG. 1;
  • FIG. 4 is an enlarged fragmentary sectional view such as would be seen along the sight line 4-4 applied to FIG. 1;
  • FIG. 5 is a still further enlarged fragmentary crosssectional view representing an enlargement of the encircled portion designated 5 in FIG. 4;
  • FIG. 6 is a fragmentary plan view of web materials wherein the plies thereof have been bonded according to the teachings of this invention, with one portion enlarged and encircled and designated 7;
  • FIG. 7 is a sectional view taken along the sight line 7-7 applied to FIG. 6;
  • FIG. 8 is an enlarged transverse sectional view seen along the sight line 8-8 applied to FIG. 6;
  • FIG. 9 is a fragmentary plan view of web material bonded together in accordance with the teachings of the invention and constituting a modification of that seen in FIG. 6;
  • FIG. 10 is another fragmentary plan view of the web materials wherein a still further modification of a bonding pattern is provided.
  • the numeral 10 represents a cross shaft which extends between frames (not shown) provided in a web handling machine.
  • the cross shaft 10 supports a bracket 11 which is fixed to the cross shaft 10. More particularly, the bracket 11 includes parts 12 and 13 bolted together by means of bolts 14 and 15. Thus, it is intended that during operation there is no relative movement of the bracket 11 relative to the cross shaft 10, nor of the cross shaft 10 relative to the frame of the machine.
  • the bracket 1 rotatably supports a notched, edge-beveled wheel 16.
  • the wheel 16 operates in conjunction with a grooved roll 17 to perform the ply bonding on a web 18.
  • FIG. 4 wherein fragmentary portions of the wheel 16 and roll 17 are depicted.
  • the roll 17 is advantageously driven (by means not shown), while the wheel 16 can be considered an idler.
  • the wheel 16 has beveled edges as at 19 and 20.
  • the roll 17 has a slot 21 defined by insert rings 22 and 23 maintained in spaced apart relation by means of a spacer 24.
  • the outer confronting edges of the plates 22 are beveled, as at 25 and 26, so as to conform to the confronting beveled surfaces 19 and 20 on the bonding wheel 16. It is believed that this can be even more readily appreciated from a consideration of FIG. 5 where the engagement of the beveled surfaces 20 and 26 is shown in further enlarged scale.
  • the sheets when bonded, have a surface appearance such as that seen in the upper left hand corner of FIG. 6 where two relatively elongated depressions 27 and 28 appear. Also seen in the upper left hand corner of FIG. 6 is a portion of a prior pair of depressions 29 and 30. Interposed between the successive pairs of depressions 27-28 and 29-30 is a relatively undepressed, unbonded area 31.
  • the unbonded area 31 can be seen readily in FIG. 7.
  • the length of the depressions (or compressed areas) 27-30 and the corresponding length dimension of the unbonded area 31 are determined by the character of the teeth 16a (see FIG. 1) on the bonding wheel 16. For example, a wide variety of tooth sizes and spacings may be employed.
  • the number of teeth in a 3-inch diameter wheel may vary from 0 to 70.
  • the spacing 31 may have an arcuate length of 0.02 to .10 inch or more, depending upon the work and apparatus employed. Wheels of this general character have been employed in the past for longitudinal perforating where they operate against hardened anvils and have required special steels because of the high pressures involved. However, according to the invention, this drawback is avoided insofar as the use of relatively exotic materials of construction is concerned.
  • a thickness of the spacer 24 of the order of about 0.02 inch is advantageous.
  • the angular extent of the beveled surfaces 25 and 26, viz., the dimension A in FIG. 5, is about 0.005 inch.
  • FIGS. 1-3 for the purpose of explaining one embodiment of a means for loading or applying force to the bonding wheel 16. It will be appreciated that a variety of techniques can be employed for this purpose, particularly in view of the relatively light force that is used herein. However, the instant arrangement does permit adjustment of the bonding wheel relative to the groove (so as to accommodate for wear) without the need for varying the loading on the wheel itself.
  • the numeral 32 designates a wheel holder which is pivotally mounted as at 33 (see the middle portion of FIG. 1) on the bracket 11.
  • a pivot shaft 34 is provided which can also be seen in dotted line in FIG. 2.
  • the wheel 16 is equipped with a ball bearing 35 (see the extreme middle left hand side of FIG. 2) which permits it to rotate freely relative to the fixed shaft 36.
  • the shaft 36 is fixed within the bracket 32 by means of a set screw 37 and that the fixed shaft 36 has an enlarged end as at 38 to confine the bonding wheel 16 in position.
  • the bonding wheel is seen to be offset from the enter line of the bracket 11, and this is advantageous because an opposite hand unit can be installed immediately adjacent the one pictured in FIG. 2 so as to give relatively closely spaced lines of longitudinal bonding.
  • the wheel holder 32 is bifurcated as at 39 (see FIG. 2) to provide a pair of integral lug portions 40 and 41 (see FIG. 3).
  • the bracket 11 is likewise bifurcated to provide a pair of integral lug portions 42 and 43.
  • Each pin 44 and 45 in turn is equipped with a transverse opening so as to accommodate receipt of a cap screw 46.
  • the cap screw 46 is threaded at its end 46a, and is threadedly received within the bore provided in the pin 44.
  • the transverse bore or opening in the pin 45 provides a clearance for the shank of the cap screw 46.
  • a nut 47 is threadably received on the cap screw 46, and provides a stop for a coil spring 48. The other stop is provided by the pin 45.
  • a 99-inch wide rewinder for two-ply toilet tissue requires 44 of the assemblies, viz., the bracket 11, wheel 16, etc.
  • the ply bond units may be engaged only just before and after cutoff and for only a few feet. This makes the transfer to the new core easier, and prevents the user from unwinding the wrong plies at the beginning of a new roll. When the latter happens, the perforations do not match between the plies, and the user can get very upset.
  • the distance between the two lines may be increased from the form illustrated viz., about 0.020 inch to 1 inch or more.
  • the notches may be at an angle.
  • two ply bonding wheels with a spacer in between with the notches staggered if desired. In this case, only the outer surfaces of the two wheels would be used.
  • the anvils may be notched. This, however, is more expensive and is not preferred.
  • both the wheel and anvils could be notched, but no real advantage is seen to this approach, even if the ply bonding wheel would be driven in order to match or mismatch the notches. It would appear that the end result would only be more expensive.
