ROLL-SIDE-BEQISTEBING MECHANISM.

Application filed March 25, 1926. Serial No. 97,170.

This invention relates to roll change mechanism and has more particularly reference to means for adjusting the web roll or its supporting means lengthwise so as to sideregi'ster the web.

In the art of roll change mechanism it is now the custom to provide a plurality of web rolls and to provide a backing member, usually of a flexible character, that bears against the employed web and to bring a replenishing roll against the employed web so that the two webs or the roll and web be pasted together. When it is now attempted to move'the roll lengthwise so as to side-register the web, the flexible backing member will drag on the web or roll and is apt to tear it, and the main object of this invention is to prevent such tearlng action.

\ Accordingly the invention consists in providing means whereby, when the roll or 1ts support is adjusted lengthwise, the backing member will likewise be adiusted so that there is substantially no relative motion between the backing member and the web.

In the accompanying drawings the invention is disclosed in several concrete and preferred formsin which:

Fig. 1 is a view in end elevation and somewhat diagrammatic in form of a. device embodying one form of the invention.

Fig. 2 is a side elevation of the parts shown in F1 '1.

Fig. 3 is a detail plan view in section of part of the gearing.

Fig. 4 is a view similar to Fig. 2 but showing a modified form of the invention.

Fig. 5 is a view similar to Fig. 1 but shpwing another modified form of theinvenhon.

Fig. 6 is a vertical sectionalview on the plane of line 6-6 of Fig. 5.

Fig. 7 is a horizontal sectional view on the plane of line 77 of Fig. 6.

1 indicates a web-pulling machine such as a printing machine and 2 is a rota able support in the form of a shaft 3 having spiders 4 at its opposite ends. Spiders 4 carry a plurality of rotatable rolls, 5, 6 and 7, one of which (5) is shown employed or in feeding position. 8 is a backing member taking here the form of a flexible canvas sheet carried by shaft 9 and having weights 10 at its free end. As shown this canvas bears against roll 5 and, when it is desired to make a roll change, paste is applied to roll 6 and shaft 3 is turned by hand or a replenishing roll is otherwise moved. into position until it comes in contact with web 11 from roll 5, backing member 8 exerting sutlicien't pressure to admit of the two webs being united, and the turning movement of 3 is continued until roll 6 occupies the position of roll 5. Shaft 3 may be adjusted in various ways. For instance pedestals 12 and 13 inaybemoved carrying the shaft with it, or, as here shown, pedestal 13 may slide in ways 14 and by reason of collars 15 and 16 may'carry shaft 3 with it. In these circumstances shaft 3 ma be loose in pedestal 12, that is: it'may sli e freely in the bearing of the pedestal. Any suitable means may be provided for moving pedestal 13 and shaft 3. In the present instance there is a motor 17 mounted to slide with the pedestal, and shaft 18 of said motor carries-a bevel gear 19 meshing with a similar bevel gear 20 on shaft 21. Shaft 21 carries a worm 22 meshing with worm gear 23 on shaft 24 and the end of this shaft is threaded as at 25 to engage an internally threaded bushing 26 carried by the framework independently-of the pedestal and consequently rotation of threaded shaft 25 will move the pedestal in one direction or the other in accordance with the direction of rotation, and will thus move shaft 3 and the spiders endwise. Motor 17 is of the reversible type.

Shaft 9 is slidable in bearings 27 and has a threaded portion 28 engaging internally threaded bushing 29 carried by bracket 30 of the framework. Said bushing also carries-a sprocket 31 connected by means of chain 32 with s rocket 33. Sprocket 33 is mounted on sha 34 which latter is slidable with respect to the sprocket and is, like shaft 24, carried by pedestal 13. Spur gears 35 and 36 connect shafts 24 and 34.

It will now be seen that when shaft 3 is moved endwise shaft 9 is likewise moved and in synchronism therewith and consequently backing member 8 is shifted in synchronism with the web roll against which it bears.

In Fig. 4 is shown a modified form of the invention in which the backing member consists of two canvas sheets 37 and 38 mounted on shaft 9.

In Figs. 5, 6 and 7 is shown a second mod ified form of the invention. Here backing member 39 is in the form of a canvas hung from shaft 9 as before, but in addition thereto the lower end thereof is anchored by no means of spring on slidable member or anchorage 41. Member 41 is moved longitudinally by the same kind of a connection as 30, 31and 32, power being derived from shaft 84 by means otsprocket 42 with the result that both shaft 9 and member 41 are moved endwise in synchronism'with support or shaft 3.

In all of the forms shownp support carrying a plurality of rolls is disclosed, but it will be understood that, if desired, support 3 may carry only one roll.-
