Definitions
- the present invention relates generally to the partition assembly making art, and more particuiariy to a novel pressure apparatus normaily located on the back table of a partition making machine for applying and maintaining the desired constant tension on a continuously fed endless web of paperboard between the punches and the grip rollers of the machine to hold an accurate register at the cut-off knife thereof, for preventing buckling of the web in critical reaches, and for reducing the braking force required to prevent overrun of the grip rollers.
- an object of the present invention is to provide a novel pressure apparatus for tensioning a continuous paperboard web which satisfies the aforesaid long-felt need.
- the present novel pressure apparatus for ten sioning a continuous paperboard web includes an elongated base plate over which the paperboard web passes and through which the pressure apparatus is supported in operative relation with a partition assembling machine, a pressure cylinder unit supported above the base plate, a pressure foot suspended from the pressure cylinder unit for transfer of pressure to a paperboard web, spaced runners selectiyely supported beneath or at each side of said presser foot, web guides, control and actuating means for said pressure cylinder, and interconnecting elements.

- FIGURE 12 is an end view thereof.
- 20 indicates generally pressure apparatus made in accordance with the principles of the present invention, illustrated as operatively mounted on the web feed-in end or back table of a partition assembling machine 22.
- the pressure apparatus 20 includes an elongated base plate 24 which is bolted to the longitudinal frame side members 25 of the assembling machine 22.
- An upwardly opening channel 26 runs the full length of the base plate 24.
- Two spaced aligned angle brackets 28 are welded to the base plate 24, to the vertical portions of which is bolted a heavy elongated member 29 of angle crosssection with the horizontal flange 30 spaced from the base plate 24 (FIGS. 2, 3, 5, 6 and 8).
- An air actuated pressure unit 32 is mounted midway on top of the flange 30 by machine screws.
- the unit 32 is of standard construction obtainable on the open market and includes a depending reciprocable rod 33 extending through an opening 34 in the ange 30 (FIGS. 2 5).
- the air line 36 is connected into a source of air under pressure and that the gauge-regulator 37 is adjustable by means of a hand knob 38 to provide a constant supplyy of air under predetermined pressure to the unit 32 to maintain the spring therein under such selected constant pressure for a purpose described below. Air is exhausted from the unit 32 and the line 36 by the usual valve at the gauge-regulator 37.
- the depending rod 33 has a reduced lower portion 39 from which is pivotally suspended a U-shaped presser foot 40 by means of opposed angle brackets 41 secured to the bight portion 42 of the presser foot 4t) by machine screws, the reduced portion 39 depending between said angle brackets 41 and pivotally connected thereto by a horizontally disposed peened-over pin 43 (FIGS. 4 and 5).
- the presser foot 40 includes parallel vertical legs 45 to the outer surface of each of which substantially centrally thereof are pivotally mounted two vertically aligned rollers 46 by means of stub pivot shafts 47 aaeaeos 3 threadedly mounted in the legs 45 (FIGS. 2, 4 and 7).
- the rollers 46 track vertically against blocks 48 welded to the angle member 29, one block 48 being disposed at each side of the presser foot 40. It is to be understood that the presser foot 40 has minimum play longitudinally of a web passing thereunder, or otherwise accuracy at the cut-ofic knife of the machine 22 would be impaired. The rollers 46 assist in obtaining the necessary close tolerance.
- a bar 50 is mounted forwardly of the base plate 24, being mounted on the latter by means of brackets 51 which are secured beneath the base plate 24 by machine screws (FIGS. 2, 3 and 9).
- the bar 50 is held against removal by setscrews 52 (FIG. 2).
- Mounted on the rod 50 and extending rearwardly therefrom in positions beneath the presser foot 40 and above the base plate 24 are resilient runners or holddown straps 54 of the construction clearly shown in FIGURES 2, 3 and 10. It will be noted from FIGURESv 2 and 4 that the presser foot 40 rests upon the runners 54 and that the exemplarily illustrated paperboard web 55 passes beneath the runners 54 and across the base plate 24.
- a web guide plate 56 of the configuration clearly shown in FIGURES 2-4, 8, 9, ll and 12, isadjustably mounted on the base plate 24 at each side of the presser foot 46.
- Each guide plate 56 has a main blade portion 57 having a shoulder 58 along the edge which faces the presser foot 40 and beneath which the paperboard web 55 passes, as is clear from FIGURES 3 and 4.
- the guide plate 56 also includes an anchoring portion 59 having a slot 6i) therein, a downturned lip portion 61 at one end of the blade portion 57 for abutting the front edge of the base plate 24, and an aligning, locking portion 62 which extends a little downwardly from the plane of the blade portion 57 and engages in the channel 26 of the base plate 24.
- a machine screw 63 through the slot 60 maintains each guide plate 56 in selected position of adjustment by engagement in one of several threaded openings 64 spaced along the base plate 24 (FIG. 2).
- the present novel pressure apparatus is adapted to function eiciently in maintaining the desired tension on the paperboard web 55 being drawn through the partition assembling machine 22.
- the pressure can be quickly increased or decreased without stopping the machine 22 by manipulation of the knob 38.
- Paperboard of different Widths and thickness can be accommodated, it being understood that the space below each shoulder 58 is of suicient depth to receive paperboard of maximum thickness.
- FIGURE 1 there is shown diagrammatically the layout of the partition assembling machine 22 and the relation thereto of the pressure apparatus 20.
- the machine 22 includes forwardly disposed web feeding rollers 70 which pull the web 55 and feed it a predetermined distance beyond the reciprocating cut-olf knife 71 into interiitting relation with longitudinally moving edgewise disposed partitions, the knife 71 severing segments successively as intertted in the usual manner.
- the web 55 is drawn from a roll 72 and passes over, under and through rollers 73, 74, and 75, respectively, and over a hold-up plate 76 before reaching the pressure apparatus 20 mounted on the back table of the machine 22.
- Rollers 77 may also include slitting discs.
- pressure apparatus for maintaining desired constant tension on a continuous web of paperboard material, and the like, being fed to a partition assembling machine
- a support for mounting said pressure apparatus in operative relation to a partition assembling machine, said support including an area over which a web passes in fully supported relatiton therewith, a pressure unit mounted on said support in spaced relation thereabove, said pressure unit including a reciprocatable depending rod and means for maintaining said rod in a position of rest when said pressure unit is not under pressure, means for supplying pressurized air to said pressure unit under a selected constant pressure, means for varying said supplied pressure, a presser foot suspended from said rod for reciprocation therewith and adapted to apply pressure to a web of material, runners of resilient material mounted on said support and adjustable laterally of a web of paperboard, said runners being adapted to engage a paperboard web in holddown relation, said runners being independent of said presser foot and being selectively locatable beneath said presser foot and laterally thereof, said presser foot being provided with rollers functioning to limit movement thereof
