This invention relates to a machine for wrapping and labelling newspapers, magazines and the like and has as its object the provision of a comparatively simple machine into which such articles and their labels may be introduced, and by a rotary motion, be rolled, fastened with adhesive and ejected from the machine.

According to this invention the machine consists of a framework designed to receive the articles to be folded, a main shaft or axle equipped with an end or head member on which are mounted a plurality of planetary gears which mesh with a stationary gear or sun wheel mounted concentrically of the said main shaft. The planetary gears are fitted on the ends of engaging means such as hollow or split winding or wrapping spindles, in such manner that as the head member is caused to rotate the planetary gears being in mesh with the sun gear will rotate, carrying with them in rotation the said spindles.

The main shaft is caused to rotate for part of a revolution, remain stationary for a period, and again rotate for a further part of a revolution, the number of part rotations and stops in each complete rotation being the same as the number of planetary gears and spindles. For instance where three operations requiring separate pauses only are being performed, such as feeding in, gumming and ejecting a paper, it will only be necessary for three planetary gears and spindles to be used. However the number of spindles may be increased together with the planetary gears and is not limited to any precisenumber. i

.As the spindle, which has received the end of the paper and the label'moves from the feeding in position to the gumming position it is caused to rotate and thus rolls the paper and label around it. During the period at rest the end of the label is brushed with adhesive, when the paper is further rotated while being moved to the ejecting position whence during the next pause it is ejected from the machine, 'thespindle rotating further to the feeding in position to receive the end of another paper and label.

The'spindles are geared so that at each stop the opening therein is radially directed outward- 1y. At each rest period for the spindles a paper is inserted in the spindle at the feeding in position, adhesive is brushed on the end of the label at the gumming position andthe paper is ejected from the spindle at the ejecting position.

When it is desired to roll a paper on itself without a separate label, the adhesive is applied at thengummin position to the end of the paper 1- se As the spindles are supported at one end only the head member in which they are mounted is specially designed as with two spaced discs carrying bearings (in which the spindles rotate) to enable the accurate alignments of the spindles to be maintained. The main shaft may have the above-described intermittent movement of rotation transmitted to it by any suitable means known to those skilled in the art, but in a preferred construction the means consist of a ratchet and pawl arrangement.

The spindles may be of selected size to suit the type of paper being wrapped and may be of any desired shape. While this motion of the ejector plate may be effected in various ways, in a preferred construction it is done by a cam and lever link motion.

To ensure that the paper is wound to the desired degree of tightness on the spindles springloaded pads mounted on :the main shaft press against the spindle, or the outer fold of the paper or label being wound thereon as the case may be.

In a modification "the springs may be carried on arms attached to the end member.

In order to describe the invention more fully, reference will now be made to the accompanying drawings which depict .a form of the invention in which four spindles and planetary gears are used and wherein:

Figure 1 is a fragmentary diagrammatic end view of the machine, while Figure 2 is a side elevation thereof, and

Figure 3 illustrates a suitable pawl and ratchet assembly for intermittently rotating the main shaft of su h machine.

The machine as depicted consists :of a suitable framing adapted to support the integers now to be described.

A main shaft or axle i6 is mounted in suitable bearings 18 and 28 extending from the machine framing and carries a fore end member or head 3 fixed thereon and formed of spaced plates so as to keep certain spindles 1 later referred to carried therefrom in alignment and in a'rigid manner.

At the fore end the main shaft It carries a ratchet gear 4 ,fixed thereon which is engaged by a pawl 6 pivotally carried on arr-oscillating arm 5 having free semi-rotary movement on the said main shaft 16 and being operated by a cam, eccentric or the like (not shown) driven from any suitable power source in known manner after the forms flvariousrmechanis ms to intermittently rotate the said main shaft It.

The spindles I are arranged at equally spaced intervals about the head member 3 extending therefrom parallel with the main shaft I6 and are rotatably mounted in said head and pass therethrough at their fore ends and each have mounted thereon a planetary gear I meshing with a sun wheel 2 concentric with the main shaft i6. These spindles 1 form wrapping members and have an elongated opening I! therein extending in from the outer end to a point near the head 3 and are appropriately shaped to receive the end of a paper or magazine indicated at IS in Figure 1, together with a label indicated by numeral I2, and are later referred to in the description of operation. In this construction the wrapping spindles l are four in number but this may be varied, as previously mentioned.

Inwardly of each wrapping spindle 1 there is a pressure pad 8 mounted to move towards its related spindle by means of a compression loading spring 25 secured at the outer end to said pad 8, and at the other end fixed to a collar 9 fast on the main shaft I6. These pads 8 are suitably curved or otherwise shaped to more or less conform to the curvature of the said rollers 'a' which they are adapted to resiliently contact in such a manner as to co-act therewith in a rolling wrapping action exerted upon the paper I3 and label I2 in the action of wrapping same, as later more fully described.

At one side of the machine preferably in a horizontal plane, there is a guide for the reception of a paper and its label to lead same to a wrapping roller 1 as each is successively positioned opposite thereto with its slot I? in register. This guide as shown consists of a lower guide plate I and upper guide plate 26 suitably spaced apart and supported on or from the machine framing. If desirable these plates may be adjustable so that they can be set apart or moved closer together.

At the other side of the main shaft .I6 and its associated mountings a gumming table I4 is arranged at a position where each wrapping spindle 1 is adapted to register with a protruding portion of a label extending beyond the paper I3 and which label end is deposited on the said table while a gumming brush or other applicator 36 supplies gum thereto.

At a position at one side of the main shaft I6 say on the underside at a point where each wrapping roller 1 is positioned successively verticall of the shaft axis where the wrapping operation is complete, ejector mechanism is fitted in the machine framing, and consists of an 'ejector plate I 6 of toothed or slotted form having a series of equally spaced cavities therein which are shaped more or less complementary to a wrapping roller and such ejector plate I 6 is slidably positioned on a shaft I I fixed in brackets or the like (not shown) fast to or from the machine framing. The position of this shaft II is such that the ejector plate cavities each take about a portion of a wrapping roller 1 as same is advanced thereto, and the said plate rotating on the said shaft II to bring its cavities into position.

The ejector plate I6 is affixed to a collar 2%? which is also slidable on the fixed shaft II. A link I9 is pivoted at one end to the collar 26 and at the other end connects to a lever 26 pivoted at its outer end on a shaft 2i, and such lever 2e outwardly of said shaft 2I is connected by an arm 22 to a stud 24 contacting an operating cam 23 adapted to be driven in any suitable manner to synchronise the movement of the ejector '4 plate Io with the pause in rotation of the main shaft I6 and its wrapping spindles I.

In operation a paper or the like I3 and label i2 are directed through the guide opening between the plates I5-26 so that the leading ends of said paper and label are positioned in the opening I I of the wrapping spindle l aligned with what is herein termed a feeding in position A (see Figure 1). The main shaft I6 being rotated in an anticlockwise direction by means of the pawl 6 operating on the ratchet 6 the spindles 1 are rotated by their planetary gears I, and as the spindle assembly rotates, the paper I3 and label I2 are rolled about their related spindle I tension of the wrapping being maintained by the pads 6 pressed into contact with the matter to be wrapped by the springs 26. The rolling is shown at position B and at gumming position C, the paper I3 is fully wrapped, but the end of the label is protruding and gum is applied thereto, the shaft I6 and its assembly being halted during such operation. As the spindle I moves on and passes from position C to ejecting position D the wrapping of the gummed end of the label I2 about the paper is completed, and the assembly is again stopped while the wrapped paper I3 is ejected by the ejector plate In which is moved along its shaft I I for the purpose.

As one wrapped paper or the like has been ejected the spindle assembly again moves, the ejector plate Ill partially revolving on its shaft I I, the next spindle I fits into the following plate cavity.

It will be seen that in the stoppin operations an article can be loaded in, gumming and ejection effected at the positions shown in Figure '1 so that there are not separate stops for such operations.
