- ABSTRACT Apparatus for guiding webs of material in such a manner as to maintain a fixed center line regardless of the width of the web.
- a main carrier member is fixed to a base; The center line which must be maintained regardless of web width passes through the center of the vertical height of the main carrier.
- Upper and lower movable web guides are slidably mounted on the main carrier.
- An adjustment mechanism allows both the upper and lower web guides to be moved toward or away from the fixed center line simultaneously. This movement keeps both web guides the same distance away from the fixed center line to allow guiding of webs of differing widths.
- An alignment mechanism is used to initially set both web guides the same distance away from the fixed center line. This is then locked,
- This invention generally relates to web guiding mechanisms. More particularly, this invention relates to web guides which are adjustable to guide webs of varying widths. Specifically, this invention relates to a web guiding mechanism having two movable guide members which are moved. toward or away from a fixed center line to keep the web on this center line regardless of web width.
- This invention is an improvement in the guiding of webs of material, wherein it is required to maintain a constant web center line regardless of web width.
- a vertically extending main carrier having a fixed web center line passing through it, is attached to a base.
- An upper movable web guide is slidably attached to the main carrier above the fixed center line and a lower movable web guide is slidably attached to the main carrier below the fixed center line.
- An adjustment means is used to simultaneously move both the upper and lower movable web guides toward or away from the fixed center line an equal amount on both sides of the fixed center line.
- An alignment means is used to initially set the distance from the fixed center line to the upper and lower movable web guides at the same value.
- a locking means holds the alignment means in its initially set position during movement of the upper and lower movable web guides by the adjustment means.

- the apparatus of the present invention is shown in its general operational environment in FIG. 1.
- This apparatus has found its greatest utility in conjunction with the machine which is disclosed in U.S. Pat. application Ser. No. 209,751 filed Dec. 20, 1971 and having an assignee in common with the assignee ofthe present invention.
- the machine disclosed in the noted patent application is of the type which operateson a constant material infeed center line. This machine is used to produce glass containers having a thermoplastic, sleeve placed thereon. A web of material is fed into the machine and formed onto the glass container.
- the web of material enters the machine at a constant center line location, regardless of the actual height or, as it may be termed, width of the web of material.
- This has created operational difficulties in the feeding of the web in that it has been .difficult to maintain the precise center line location to the degree of accuracy that is required for proper operation.
- the present invention solves this problem, and likewise could solve a similar problem for other types of machines which require-a web'feed at a constant center location regardless of web height. While this machine and the following description require the web to be moving in a vertical path of travel,
- the portion of the entire operating apparatus shown in FIG. 1 is after the web has been removed from a supply reel, under tension, and just before the web is fed into the end use machinery.
- the entire apparatus is mounted on a base 10, which is positioned on the floor of a manufacturing area, and is level to give a precise and known elevation.
- the inspection device 14 forms no part of the present invention and therefore needs to be discussed no further.
- the movement of the web 12 is from left to right as seen in FIG. 1.
- the web 12 is guided in its path by a first adjustable web guide mechanism 16 and a second adjustable web guide mechanism 17.
- the web guide mechanisms 16 and 17 are structurally identical and differ only in their method of attachment to the base 10.
- the web 12 is passed between two rotatable guide rollers 20 and 21, which are mounted on the base 10, and held to the path of travel between the two guide rolls 20 and 21 by a fixed web guide 22.
- the second adjustable web guide mechanism 17 has two support plates 28 and 29 attached to a main carrier 30.
- the support plates 28 and 29 in turn are attached to a mounting plate 32 'which is affixed to the upper surface of the base 10.
- the first adjustable web guide mechanism 16 is likewise attached to the base 10 through a horizontally extending support plate 34.
- The'support plate 34 is actually attached to a machined pad at the rear of the base 10.
- the first adjustable web guide mechanism 16 has two support brackets 36 and 37, which are under the horizontal support plate 34.
- the support brackets 36 and 37 are attached to the main carrier 30 of the first adjustable web guide mechanism.
- FIG. 2 is a front view of the second adjustable web guide mechanism 17 removed from its operational environment.
- the two web guide mechanisms 16 and 17 are identical, except for their method of attachment to the base 10, and therefore the description of one of these mechanisms is sufficient as a description for both.
- the web guide mechanism 17 has an upper movable web guide 40, a lower movable web guide 42, and a central fixed web guide 44. All of the web guides 40, 42 and 44 have a curved surface over which the web 12 rides. This may best be seen with reference to either FIG. 1 or FIG. 5.
- the rear portion of the web guides'40 and 42 have two slots'cut out to allow defining a key.
- the key for web guide 40 is designed as key 48 and the key for the web guide 42 is designated as key 49.
- the slots 46 and 47 are cut sufficiently wide to allow them 'to completely clear the main carrier 30.
- the keys 48 and 49 are engaged in a keyway 50 formed in the main carrier 30, thus allowing a slidable connection to the main carrier 30.
- the upper movable web guide 40 and the lower movable web guide 42 may slide up and down with respect to the main carrier 30-with the keys 48 and 49 engaged in the keyway 50 maintaining the properorientation of the movable web guides 40 and 42.
- a cap 52 is attached to the main carrier 30 with two screws 53 and 54. Rotatably supported in the cap 52 is a shaft 56.
- the upper movable web guide 40 and the lower movable web guide 42 are rotatably mounted on the shaft 56.
- a handle assembly 58 has a hub portion 60 pinned to the shaft 56. Rotation ofthe handle assembly 58 will in turn rotate the shaft 56, which will move the upper movable web guide 40 and the lower movable web guide 42 toward or away from the fixed web center line, designated as C.”
- the handle assembly 58 is not provided with any locking mechanism, and thus, to preventaccidental movement of the web guides 40 and 42, provision is made to lock the web guides 40 and 42 into any position at which they are set. This is accomplished by two spring-loaded screws 62 and 63, which are attached-to the face of the upper web guide 40, which is remote from face guiding the web 12.
- the screws 62 and 63 extend through elongated slots 64 and 65 which extend completely through the main carrier 30.
- the spring .load on the screws 62 and 63 tends to hold the location with screws 72 and 73, which extend through the main carrier 30 and hold the central fixed web guide 44 in a known location.
- the adjustable web guide mechanism 17 is shown partially in cross section.
- the shaft 56 is not sectioned in order to more clearly show its distinct and important portions.
- the upper movable web guide has a lip 74 formed in its front surface.
- the lip 74 defines an edge which prevents the web 12 from moving beyond this edge.
- the lower movable web guide 42 has a lip- 76 formed from its front face, the lip portion 76 serving to prevent the web 12 from falling below this fixed location. It should be clear therefore, that as the web 12 travels over the web guides 40 and 42, it is trapped between the two lip portions 74 and 76.
- the central fixed web guide 44 serves to support the central portion of the web 12 and prevents flexing motion of the web 12 during its travel.
- the key portion 48 of the upper movable web guide 40 and the key portion 49 at the lower'movable web guide 42 may be seen to be in engagement with the keyway 50 in the main carrier 30.
- the upper movable web guide 40 is formed with a hole 75 extending completely through it parallel to the face which contains the lip portion 74.
- the lower movable web guide'42 is formed with a hole 77 completely through it also parallel to the face containing its lip portion 76.
- the shaft 56 extends through these holes in the web guides 40 and 42, and also extends through a relief portion formed in the central fixed web guide 44.
- the upper movable web guide 40 is made with a recess 78, connecting with the hole 75, behind the face with the lip portion 74.
- a cylindrical nut 79 Inserted in the recess 78 is a cylindrical nut 79, which has a threaded opening extending completely through it.
- the lower movable web guide 42 has a corresponding recess 80, connecting with the hole 77, formed in it, also behind the face which contains its lip portion 76.
- a cylindrical nut 81 upper movable web guide 40 in whatever position it is inserted in the recess portion 80 of the lower movable web guide 42, the cylindrical nut 81 having a threaded opening extending completely. through it.
- the shaft 56 has an upper portion 84, which is of a somewhat smaller diameter than the rest of the shaft 56.
- the hug 60 of the handle assembly 58 is pinned to this upper portion 84 with a roll pin 85.
- first threaded. portion 86 begins.
- a distinct shoulder is formed at the transition point between the portions 84 and 86.
- first threaded portion 86 ends, and a short transition portion 88 which is unthreaded, connects the first threaded portion 86 with a second threaded portion 90.
- the first threaded portion 86 is preferably made up of a righthand thread. This right-hand thread is in engagement with the threaded hole extending through the cylindrical nut 79.
- the second threaded portion 90 is preferably made up of a left-hand threaded portion and is in threadable engagement with the threaded opening extending through the cylindrical nut 81.
- the cap 52, the handle assembly 58, the shaft 56, the nuts 79and 81 and the configuration of the movable web guides 40 and 42 make up an adjustment means for simultaneously moving both the upper movable web guide 40 and the lower movable web guide 42 toward or away from the fixed center line C an equal amount on both sides of the center'line C.
- the upper portion of the first threaded portion 86 of the shaft 56 and the upper portion 84 of. the shaft 56 maybe seen in perspective.
- the opening which extends through the cap 52 through which the shaft 56 extends is a threaded opening.
- a threaded bushing 96 is threadably engaged in this opening through the cap 52.
- the upper portion of the bushing 96 terminates in a hexagonal configuration 97, which may be engaged with a wrench for rotation.
- a lock nut 98 which is a locking means for holding the alignment means in its initially set position, is engaged with the threads of the bushing 96 and may be tightened to prevent accidental movement of the bushing 96.
- a flanged bushing 100 extends between the lowermost portion of the hub 60 of the handle assembly 58 and the shoulder 101 of the shaft 56, the shoulder 101 being defined by the difference in diameters of the upper portion 84 of the shaft 56 and the first threaded portion 86 of the shaft 56. Additionally, in this situation, the flanged bushing 100 does not actually bear directly on the shoulder 101, but rather bears on a hardened washer 102, which is placed on the shoulder The hardened washer 102 is an optional feature and is inserted merely to help protect the threads of the first threaded portion 86. It is not an absolute requirement and could be eliminated and properfunctioning would still result.
- the lock nut 98 may be tightened again to hold the bushing 96 in this fixed location.
- the handle 58 may be rotated to move the upper web guide 40 and the lower web guide 42 toward and away from the center line C, and this movement will give exactly corresponding displacement for both the upper and lower web guides 40 and 42.
- the flanged bushing l 00 fmay be split into two pieces for assembly.
- FIG. 6 the upper movable web guide 40 and the lowermovable web guide 42 are shown removed from the main carrier 30.
- the key 49 in the lower movable web guide 42 is seen as being defined by two slots I06 and 107.
- the slots 106 and 107 like the corresponding slots 46 and 47 in the web guide 40, are sufficiently wide to clear the main carrier 30 and allow free movement up and down of the lower movable web guide 42.
- Tapped holes 110 and Ill accept the spring-loaded screws 62 and 63 for the upper movable web guide.
- Tapped holes 112 and 113 accept the spring-loaded screws 68 and 69 for the lowermovable web guide 42.
