Figure'Z-is a perspective view of the fi-rst'tyingstation looking from the inlet endo'f 'th ma'ehineshow-11in Figure l; with the present improvement shown in position adjacent the tying ring and with the string carrying tying ring position" tice in' the past to link stuffed sausage casings by pinching a length of the stuffed casing off with the fingers and manually twirling the portion of the casing disposed betweenxthe fingers. This twirling motion causes the casing to be twisted at the-points where it is pinch'ed'bythe fingers and linking is thus accomplished. This operation is repeated at spaced points to complete the linking of the entire casing.

Recently maehines' have been proposed for accomplishing; the linking of stuffed casings and,

in. certain of these machines, astring": is tightly wrapped? around a casingrto pinch the casing downto form the individual links; One. form,

The stuffed casing is delivered from the conveyor II through the two tying stations l2 and I3, and passes from these stations to the outlet conveyor belt I4. The feed. through the machine is intermittent and the stuffed casing is stopped at the two tying stations, after a predetermined length of easing has been driven through the machine, so that while the casing remains stationary the tying means may be driven to link the casing." Each of the tying stations wraps a string around the casing and each string is then severed, whereupon the feed means becomes energized to carry the casing forwardly a predetermined distance to present the following portion of the casing to the tying means.

The tying means itself is best shown in Figure 2 .and basically it includes a rotating ring I5 which'is adapted to be driven aroundthe casing While it is held stationary, in a generally concentric relation, within the ring. The string Ifi for tying the casing is deliveredthrough suitable guiding and tensioning means and the free the space between the inner surface of the ring and the stuffed casing passing through the ring (see Figure 2), so that When the string is drawn ,taut between the casing and hook II, upon comend of the string is engaged on'the side wall of I the; rotating ring; I5 by hooks I! and I8. The

hooks are driven to engage the string by cam means. operated in timed relation to the movement of the casing through the tying station so that the string is clamped on the ring to be carried around the casing in a sequence which will be more fully described below.

. When the string is engaged by hooks I] and 1 I8 and the ring I5 is rotated, the string is carried'around the casing. Means are provided to cooperate with the ring to measure off a required length of string and when a proper length has been pulled through the delivery means, the

tying is completed by. driving the ring around,

the'casing a plurality of times. Simultaneously with the wrapping of the string around the casing, the string is pulled back by the delivery means to tension it in a manner to draw the casing in so as to form the separation between the individual links.

- After the string has been carried around the casing and; drawn in to provide the ends of each link, thezend of -the string is released from books 3 I! and I8 and these hooks continue on their way i V to engage the string between the casing and the When the hooks again engage the string the ring is driven to draw the string delivery means.

string down from the casing and hold it taut while a knife I9 is driven into engagement with the stretched string to sever it.

. So much of the machine as has already been:

of the string on a shearing edg for cooperation with the knife is best seen in the plan view of anvil 29 (Figure 9) wherein the string is shown laid upon hearing edge 30 during one phase of.

the tying operation. It is there seen that the shearing edge 30 is positioned to cooperate with the cutting edge of knife I9 so that the string is positively engaged between shearing meansv whereby it is severed. The fixed shearing edge 30 i normally disposed toextend somewhat into v pletion of the tying operation, as shown in Figure 8, the shearing edge 30 will be projected across the path the string normally follows in being wrapped around the casingto insure that proper shearing will always take place.

Anvil 29, upon which the shearing edge 30 is formed, is fixedly supported from the base plate 3| of the machine, and it is necessary, during the wrapping of the string around the casing, to provide means for directing the string around one end of the fixed shearing edge which, as stated above, projects across the normal path the string would follow in being wound around the casing. Thus, referring again to Figure 9, cam surface 32 is shown which is preferably formed integral on the anvil, against which the string is engaged as it is carried around by the ring during the tying operation; The string passes over the cam surface 32 to be deflected from its normal path and then .it falls onto the shearing surface 30, as the hooks I! and I8 carry the free end of the string around the lower half of the rings travel. As the hooks pass upwardly and over the top of the casing, the string is first drawn taut and then it slides off of the sloping cam surface 32 and the shearing edge 30, to be.

drawn tight around the casing.

When the winding operation has been com wall of ring I5, is a forwardly'projeoting nosepiece 33 which is adapted to engage and guide the string when it is released from the measuring means, as shown in Figure 4. When the string is slack at this point'in the cycle, it mightv possibly loop itself completely over the anvil so that the tying operation would be interrupted. Nosepiece 33 has been provided, to prevent this from happening. Thenosepiece 33 is also inclined downwardl at an angle from the anvil 29 as is'best shown in Figures 3 to 3 so that as the knife is reciprocated inwardly, it will first engage the nosepiece 33. The knife is lifted by the inclined surface of nose 33, against the tension-of a spring. through which the knife'is fixed to its carrying arm and a tight and exact cooperation between the anvil and knife-edge thus results. knife on the nosepiece guides the knife edge into exact alignment with the shearing edge 30 and positive cutting of the thread is accomplished. It is to be noted that the knife in passing over the nose 33 and the shearing edge 3!! engages each of these surfaces tightly, and a self-sharpening action takes place.

In the preferred form, the knife-edge is provided with an angularly ground cutting edge 34 inclined in a manner to trap the string between the tip 35 of the knife-edge and the shearing edge 30 whereby the string cannot escape from between these two elements during the cutting. As the knife moves forwardly, the string is thrown The bearing of the,
