Abstract

A method and an apparatus are provided for feeding a web of thin, flimsy material to a wrapping station located in a wrapping machine. A sheet of the thin, flimsy material is cut from the web after it has been fed to the wrapping station. During the feeding process, a continuous web of thin, flimsy material is moved along a path from a supply. While in the feeding process, continuous, longitudinal pleats are formed in the continuous web while it moves along said path. The pleats are effective to stiffen the material without causing a transverse stress therein, thereby enhancing its capacity to be fed to the wrapping station. The feeding assembly may be used in combination with a wrapping machine for wrapping packages with a thin, flimsy sheet of material. A more specific embodiment includes an assembly providing means for placing continuous, longitudinal pleats in a thin, flimsy web of material. In this specific embodiment, the web of material is fed vertically downwardly into the wrapping machine at which point sheets are cut from the end of the web for placement around a package.

[21] Appl. No. 824,561
[22] Filed May 14, 1969 [45] Patented Oct. 12, 1971 [73] Assignee Scandia Packaging Machinery Company North Arlington, NJ.
[72] Inventor [54] WEB-FEEDING MEANS AND METHOD Primary Examiner-Wayne A. Morse, .lr. Attorney-Markva & Smith ABSTRACT: A method and an apparatus are provided for feeding a web of thin, flimsy material to a wrapping station located in a wrapping machine. A sheet of the thin, flimsy material is cut from the web after it has been fed to the wrapping station. During the feeding process, a continuous web of thin, flimsy material is moved along a path from a supply. While in the feeding process, continuous, longitudinal pleats are formed in the continuous web while it moves along said path. The pleats are effective to stiffen the material without causing a transverse stress therein, thereby enhancing its capacity to be fed to the wrapping station. The feeding assembly may be used in combination with a wrapping machine for wrapping packages with a thin, flimsy sheet of material. A more specific embodiment includes an assembly providing means for placing continuous, longitudinal pleats in a thin, flimsy web of material. 1n this specific embodiment, the web of material is fed vertically downwardly into the wrapping machine at which point sheets are cut from the end of the web for placement around a package.
WEB-FEEDING MEANS AND METHOD This invention relates to means for feedingthin, transparent webs to wrapping machines and provides means for forming longitudinal pleats in the web to stiffen the web. The pleats are formed in two'stages with two pleats being formed in the first stage and two more pleats being formed in the second stage.
The invention has for its salient object to provide simple and practical means for stiffening a sheet or web of thin film material thereby facilitating the feeding of the material to a wrapping machine.
BRIEF DESCRIPTION OF DRAWINGS Other objects of this invention will appear in the following description and appended claims, reference being made to the accompanying drawings forming a part of the specification wherein like reference characters designate corresponding parts in the several views.
FIG. 1 is a front elevation of a machine embodying the invention;
FIG. 2 is a sectional elevation taken on line 2-2 of FIG. 1, looking in the direction of the arrows;
FIG. 3 is a schematic plan view of a web pleated;
FIG. 4 is a sectional elevation taken substantially on line 4- 4 of FIG. 3, looking in the direction of the arrows;
FIG. 5 is a rear elevation of the machine shown in FIG. 1;
FIG. 6 is a sectional elevation taken substantially on line 6- 6 of FIG. 5, looking in the direction of the arrows;
FIG. 7 is an elevational section of the machine shown in FIG. 6 but showing the hinged frame open to receive the continuous web;
FIG. 8 is an edge view of the unpleated continuous web;
FIG. 9 is a sectional elevation taken substantially on line 9- 9 of FIG. 5, looking in the direction of the arrows; showing the first set of pleats formed in the machine; and
FIG. 10 is a sectional elevation taken substantially on line Ill-10 of FIG. 5, looking in the direction of the arrows.
In the embodiment of the invention illustrated in the drawings there are shown three shafts 10, 11 and 12 supported in upright side frames 15 and 16. The top shaft 10 has mounted thereon a roller 17 over which the continuous web S of thin transparent material, such as polyfilm, is fed into the pleating device. One end of the shaft 10 has mounted thereon a gear 20 which meshes with an idler gear 21, which in turn meshes with a gear 22 mounted on the shaft 11. The gear 22 also meshes with a gear 23 which meshes with a gear 24 on the shaft 12.
The continuous web of film is guided around the roller 17 and passes downwardly between the roller 25 on the shaft 11 and idler roller 26 which is mounted on a shaft 26A in a vertical frame or bracket 27.
The shaft 12 (FIG. 5) has three rollers 28, 29 and 30 which coact with rollers 31, 31A and 31B mounted on a shaft 32 in the vertical frame or bracket 27. These rollers not only draw the film through the second pleating stage formed by bars 40 and 43, but also hold the first pleating intact. The vertical frame or bracket 27 is pivoted at 33 and is held in the position shown in FIG. 6 by a toggle spring 34 which is mounted on a pin 35 and surrounds the pin below a toggle handle 36, which is connected by a link 37 to the vertical frame or bracket 27. The handle 36 which controls the toggle is shown in FIG. 6 where the vertical frame or bracket is upright.
The vertical frame or bracket 27 has mounted on its lower end a plurality of vertical grooved bars 40, 41 42 and 43 which are connected as at 44. The grooved bars coact with vertical strips 45 mounted on stationary plate 45A. When the parts are in the position shown in FIGS. 6 and 7 they form vertical pleats in the continuous web of material being fed downwardly through the machine and the pleats as shown in FIG. 9 and 10 stiffen the web of thin, flimsy material to permit its being fed through an opening or slot 46 in a support or platform 47.
The single roller 25 on a shaft 11, coacting with the single roller 26 mounted on shaft 26A in frame 27, draw the film through the first pleating action by grooved bars 41 and 42. In this manner the pleats are formed in two stages, two pleats being shown in FIG. 8 and four pleats being shown in FIG. 9. It
will be obvious that when the pleats are formed the width of the material is changed by each set of pleats. By the arrangement of rollers shown the pleats are held intact and thusor tension during the pleating operation, the package in the wrapping machine will be wrapped with a thin, flimsy sheet of material.
The revolving knife 48 is carried by shaft 50driven from a suitable source of power which through a chain of gears 52, 53 and 54 drive shafts 10, 11 and 12.
From the foregoing specification it will be evident that the continuous web of material as it is fed through the machine will be pleated vertically in two stages in order to provide stiffness for the material to be fed.
After the web S has reached the wrapping station, a sheet of the thin, flimsy material having no stress therein is ready for use.
Although one specific embodiment of the invention has I been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention.
