To all whom it may concern: 4
Be it known that I, PAUL RIssMANN, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Machines for Sewing Covers on Cores, of which the following is a specification.
This invention relates to machines for wrapping and sewing a cover on a core. It is more especially designed to wrap the trimmlng up on a robe cord for an automobileand sew the two edges of the trimming together. This it accomplishes automatically by the mechanism hereinafter described.
In the drawings,
Fig. 1 is a plan view of the machine.
Fig. 2 is a front elevation of the same.
Fig. 3 is an end elevation of the same taken from the left in Fig. 1. F'Fig. 4 is a section on the line 4-4 of ig. 5 is a section on the line 5-5 of Fi 1.

Fig. 10 is a side elevation of the needle guide.
Fig. 11 is a section on the line 1'1-11 of Fi I n making a robe cordfor an automobile closed body a flexible core or rope is used made up of a core wound about one or more center wires. This core is a separate article of manufacture It is the object of this invention to cover this rope or any core (flexible or not) with a cover. The function of the machine is to take this previously prepared core, guide and feed the same into the machine, and coincidentally guide and feed the trimming or cover into the machine, folding the same around the core, prepare the seam and sew the seam edges together by a whip-stitch that not only holds the on the line 66 of on the line 74 of on the line 8-8 of edges together but acts drops the loop e and as a binding for the seam edges.
a designates a machine housing which contains the operating mechanism for a whip-stitch or overcast chine. This sewin machine is part of the prlor art and no c aim is made to the specific constructionof the actuating parts of the sewing machine, hence the same is not lllustrated in detail. Suflice it to say thata looper b is operated by suitable mechanism stitch sewing main the housing a to hookunder the thread 0, as shown in F 1g. 8, and carry the loop to the opposite side of the seam as shown in Fig. 8 by the dotted lines, while the needle (5 is drawn back out of the material and again pierced into the material through the newly formed loop e (F ig.v.9). The looper then passes around to the right hand side of the seam, as shown in Fig. 8 and again picks up the thread 0 from the needle 03 that has pierced through from the opposite side and the looper again travels to the left hand side of the seam forming the loop f. In the meantime the needle has been drawn out of the material and the feeding of the material forward draws the loop obliquely backward, as is shown in Fig. 9. The needle is again driven into the material at a point somewhat to the rear of the point at which it was taken out and at a point included in the loop f. This process is repeated at each cycle of movement of the looper and at each complete reciprocation of the needle into the work and on The intermittent feeding of the work forward is accomplished by a concaved idler feed roller 9 and a concaved roller it provided with spikes i adapted to pierce the trimming and the rope and pull the same not only by the stitching mechanism but through the guide devices to be described. This roller is power driven by the spiral gear 10 and driving gear 11. The guides are supported b the brackets 12 bolted to the elbow 13. he elbow 13 is clamped to the hanger 14. The driving roller shaft is supported in a boss 15 in the machine housing and the idler has a shaft bearing clamped to the elbow 13.
The core or rope is designated 9'. This comprises a previously prepared flexible rope which is fed in between the rollers by the core guide is. The trimming material is in the form of a flat strip Z. This strip is taken into the guide in near fiat condition. The trimming guide is designated m and comprises a metal strip turned up at the edges as shown in the section 4-4 and slightly concaved. The top n is soldered on to this strip and as one progresses forward along the guide the concavity becomes of shorter radius, as is evident by comparing the sections shown in Figs. 5 and 6. This tends to double up the strip of trimming material Z. Between the points where the sections, Figs. 5 and 6, are taken, the core guide is is soldered onto the trimming guide m (compare Figs. 6, 1 and 2). Between the section lines 66 and 7-7 of Fig. 1 the core guide gradually drops down completely within the trimming guide which has now assumed the shape of a cylinder. It will be seen by comparing Figs. 5 and 6 that the edges of the trimming guide gradually fold over into a head to fold back the edges of the trimming material and that as these folded-over edges of the trimming leave the bead portion 0 of this guide they are turned in under, as shown in Fig. 7, and over the rope j. The partition 1 prevents the turned-in edges opening up. It will be seen by comparing the run of the guide from sections behind 7-7 to 8-8, Fig. 1, that the guide gradually diminishes in diameter, thereby causing the turned-over edges of the trimming material to flatten out, as is shown in Fig. 8, and forcing the two edges into abutting relation, as shown in Fig. 8.
At this point the sewing operation already I described takes place. The needle, as shown in Fig. 8, pierces the turned-over edges of the trimming and also the upper portion of the rope j, the looper grabs the thread 0, pulls the loop out of the needle and across to the other side of the seam, the rope and the trimmilng feedilng forward after the needle has been drawn back out of the work. The loop is now in the path of travel of the needle in the next piercing operation, the needle then advances again into the work through the loop, the looper lets go the loop, travels over the work to the opposite side of the seam, where it again hooks into the thread carried through by the eye of the needle, and the operation 1s again repeated, forming the stitches shown graphically in Fig. 9. The loop 16 guides the finished work away from the machine.
In Fig. 10 the needle guide block 00 with a needle guiding groove y is shown. This fits over the feed roll (see Fig. 1) and does not rotate therewith but is held firmly in stationary position on the end of the roller shaft. The turned-up abutment 2 bears against the work (see Fig. 8) and prevents the needle shoving the trimming back out of place.
Fig. 11 is a section horizontally through the feed rolls exposing the pointed work support 2 which extends under the trimming guide and out beyond the end and between the feed rolls to prevent the work dropping between the end of the guides and the rolls.
From the above description it will be evident that an entirely automatic machine is I provided for folding the trimming material about a rope or any core, and sewing the abutted edges of the same together. Of course, a hard core can be covered by this machine but the needle would not be adjusted to pierce the core but only the trimmmg.
What I claim is:
1. In a machine for the purpose specified, the combination of sewing mechanism, a core guide, a trimming guide arranged to fold the trimming material about the core into a seam that is stitched by the sewing mechanism, and feed rolls having concaved peripheries arranged to engage the. major portion of the trimming and core, one of which rolls is provided with spikes for engaging the core and the trimming material to pull the same through the guides.
2. In a machine for the purpose specified, the combination of sewing mechanism including a looper and a needle, concaved feed rolls adjacent the looper and the needle, 2. core guide, a trimming strip guide for folding the trimming material about the core and into a seam as the same is fed into the feed rolls, the said feed rolls being located adjacent the looper and the needle and engaging substantially the major portion of the work, but exposing the top of the core and the seam of the trimming strip, said needle reciprocating through the edges of the trimming strip and co-operating with the looper which serves to whip the thread over the seam.
3. In a machine for the purpose specified, the combination of sewing mechanism including a. reciprocating needle and a looper, feed rolls having concaved peripheries and located under the needle and the looper, one
of which is provided with feeding spikes, a
core guide, and a trimming strip guide arranged to fold the trimming strip about the core and into a seam that is passed into the feed rolls and below the needle and the looper, the said needle and looper operating to whip-stitch the thread over the said seam.
4. In a machine for the purpose specified, the combination of sewing mechanism including a looper and a reciprocating needle. feed rolls located below the looper and the needle, the said feed rolls having concaved peripheries to engage around the major porthe core and into a seam upon the core as tion of the work, a pair of guides, one a the same is led into the feed rolls and the tubular guide formin a core guide, the said needle and looper co-operating to sew 10 other a guide s upporte about the core uide the seam edges together and Whip-stitch the 5 to act as a trimming strip guide said atter thread across the seam.
