Filed Mar. 1, 1963, S01. No. 262,018 9 Claims. 01.271 59) The invention relates to sheet feeding mechanism for advancing sheets to front registering guides and has reference in particular to automatically adjustable means for bridging the gap provided in a sheet registering jtable to accommodate lateral adjustments of the side register guides.-

In the normal procedure of feeding sheets to a printing press or other sheet processing machine, the individual sheets are separated from a stack and then advanced by suitable means such as endless tapes, to the front end of a feed table where they are front and side registered before they are fed into the press. The front guides usually have a relatively fixed position regardless of the size of the sheets being processed, but the side guides must be adjustable transversely of the feed table t accommodate sheets of different widths.

Accordingly, a gap is provided in the sheet supporting surface of the feed table to permit lateral adjustments of the side guide mechanisms between maximum and minimum sheet width positions. When minimum width sheets are processed, the side guides are moved to theirinnermost position and under such circumstances the sheets are supported on a central, stationary part of the feed table. When sheets larger than minimum width are processed, however, the side guides are moved outwardly in direct relation to the sheet width and this causes a portion of the gap to be exposed. Thus that portion of each sheet between the central, stationary part of the feed table and the side guide will not be supported as it passes over the s pa To prevent fouling of the sheets under such circumstances it has been the practice heretofore to insert a series of individual bridge elements in the gap to support and guide the sheets. A variable number of said elements would thus have to be inserted and/ or removed each time the side guide is adjusted and each one must be accurately positioned and locked in place by suitable individual fastening means. The arrangements are usually inconvenient and relatively inaccessible so that the procedure is tedious and time consuming, thereby adding substantially to the make-ready time required for each job;

It is an object of this invention, therefore, to provide improved side guide gap bridgingmeans which are convenient and automatic in operation and which eliminate the need for any separate and time consuming adjustments.

Another object is to provide gap bridging means that is adapted to expand or retract automatically upon movement of its associated side guide and which presents a substantially continuous surface to support the sheets as they pass over said gap. I An object of the invention resides in the provision of gap bridging means for a sheet registering table which are disposed in transverse alignment with the side registering devices in a manner to permit convenient adjustment of the side registering devices to accommodate sheets of different widths, the said gap bridging means automaticall y supplementing the sheet supporting surface of the table for any adjusted position of the side registering devices.

Another and more specific object is to provide gap bridging elements having depending leg portions which can be pivotally joined for connecting adjacent elements 3,227,443 Patented Jan. 4, 1966 so as to form an articulated train capable of movement along with adjustable movement of its side registering device.

With these and various other objects in View the invention may consist of certain novel features of construction and operation as will be more fully described and particularly pointed out in the specification, drawings and claims appended thereto. p

The registering table 20 as best shownin FIGURES l and 2 essentially consists of a top board 21 of approximately rectangular shape and which is suitably fixed to and carried by the

frame members

22 and 23. A front transverse member 24 connects the members at the front edge of the table and additional members such as 25 extend transversely and connect the

longitudinal members

22 and 23 intermediate the table. The table consisting of the top board 21 and the connecting frame members is supported by

stationary frame elements

26 and 27 located on respective sides of the table. A transverse rod 28 extends between. the

frame elements

26 and 27 and said rod passes through a top recess 30 in the

members

22 and 23, respectively.

Directly to the rear of the top recesses the

members

22 and 23 journal the roller 31 over which pass the tapes 32 for advancing the sheets 2-9 t the forward end of the table in the well known manner. The

shafts

33 and 34 extend transversely of the table 26, through the top recesses 30; and through the frame elements to extend beyond the element 26. The pinions 35 operatively connect the shafts for simultaneous rotation, since driving means, not shown, are provided by the press and which have meshing relation with the pinions. Adjustable

side registering guides

36 and 38 are supported by the rod 28 and cross bar 25, and the

shafts

33 and 34 provide the means for operating the side registering guides for effecting a side registering action on the sheets.

At the forward end of the table immediately to the rear of the member 24 there are provided front registering elements 40 for registering the front edge of the sheets prior to their being fed to sheet processing mechanism such as a printing press. For printing press operation, oscillating gripper mechanism 41 is provided for receiving and gripping the front registered edge of the sheets and for delivering the same to the grippers 42 on the impression cylinder 43, FIGURE 1. Reference is made to the Peyerbrune et al. Patent No. 2,474,983, granted July 5, 1949 for a full and complete description of a sheet registering table having front registering elements similar to the elements 40 of FIGURE 1.

As shown in FIGURE 2 the top board 21 of the registering table is cut away on respective sides as at 42 and 43, and which form centrally of the table the front apron 44. The gaps in the table, resulting from the cut away

portions

42 and 43, and also the front apron 44 are directly over and substantially vertically aligned with the rod 28 and with the

shafts

33 and 34. As a result of the gaps in the table the side registering

guides

36 and 38 can be adjusted for sheets of different widths, the guides being moved to various positions within the gap openings toward the side edges of the front apron 44.

To supplement the sheet supporting surface of the table a preferred embodiment of the invention provides articulated elements 45 as shown in FIGURE 4 and which are connected to form sets, respectively, having location on each side of the front apron 44. It will also be observed that each set has a length just somewhat in excess of the length of its gap opening. Accordingly when the side registering guides are positioned for any adjusted sheet width, the gap openings are completely closed by the articulated elements. In fact one or two elements of each set may be disposed under a side edge portion of the front apron.

The gap bridging and sheet supporting element 45 are approximately U-shaped in transverse section, FIGURE 6, having a top horizontal section 46 and depending

legs

47 and 48. The top section 46 of each element has an integral overhanging lip portion 50 which is slightly bent in a downward direction. Also, each of the depending

legs

47 and 48 has a characteristic formation for the purpose of interlocking and pivotally connecting adjacent elements. The leg 47 of each element is bent outwardly to form a semi-circular terminal end 51 and the terminal end of leg 48 is similarly bent outwardly to form the semi-circular portion 52. The portion 51 is smaller in diameter than portion 52. More particularly in accordance with the invention portion 51 is of a size to fit within the larger portion 52 for pivotally connecting the elements. In this manner a number of the sheet supporting elements can be connected to form a set of the elements for movement as a train upon adjustment of its side registering device.

The side guides are each provided with a similar semicircular element such as 52 in FIGURE 4, to facilitate connection of the train to the guide for movement in unison therewith. Accordingly, when adjustments are imparted to the side guide the train of connected gap bridging elements will move back and forth therewith in a manner as illustrated by the broken lines in FIGURE 4.

FIGURE 4 shows a plurality of the individual sheet supporting elements 45 in pivotally connected relation whereby a train is provided which is of sufficient length to bridge the entire gap opening on the left side of the registering table when the side guide 38 is adjusted for a maximum size sheet. The track for supporting the train of the pivotally connected sheet supporting elements is provided by the transverse member 25 and the transverse bar 28. Member 25 is recessed at 53 on its right side and the bar 28 is similarly recessed at 54 on its left side. The bottom surface of the recess 53 is fiat and smooth throughout, whereas the bottom surface provided by the bar 28 is preferably formed with an upstanding projection 25. The semi-circular portion 52 of each supporting element is notched as at 56 and the notch is adapted to receive the projection 55 whereby each individual element 45 is properly supported and whereby the sheet supporting surface of the same aligns with that of the table both to the rear of and at the front of the gap openings.

The bottom surfaces of the

recesses

53 and 54 extend parallel to the paper supporting surface of the table for the length of the gap openings. However, below each side edge of the front apron 44 the bottom surfaces of the recesses dip at 57 to a slight extent so that the surfaces from the dip to the center of the table on each side are disposed on a lower plane. Accordingly the track and the supporting elements are so constructed and arranged that one or more of the elements of each set are located below the apron 44. More important is the fact that the elements in each set from the apron to the particular side registering device, either 36 or 38, not only completely fill the gap opening, but said elements are elevated so that the top sheet supporting surface thereof is on the same plane as the sheet supporting surface of the table.

The invention is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings as various other forms of the de vice will, of course, be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
