8 Claims. (Cl. 28-74) This invention relates to cotton pick sacks of the type that are used by pickers in harvesting cotton, and more particularly to an improved form of cotton pick sack that is characterized by a tubular woven body portion having a wear resistant surface .coating carried directly at one face thereof and to the method by which this improved cotton pick sack is formed.
Briey described, the cotton pick sack of the present invention is provided by weaving a tubular web with single ply portions formed transversely therein at a spacing lengthwise of said web corresponding to the length of pick sack desired, then coating spaced portions at one face of the tubular web reaching lengthwise thereof in relation to the single ply portions in a sufficient extent sack structure, all of which provides a substantial saving in both material and labor as well as providing an excellent cotton pick sack.
These and other features of the present invention are described in further detail below in connection with the accompanying drawings, in which:
Fig. 1 is a plan view showing the top surface of a representative cotton pick sack structure embodying the present invention;
Fig. 2 is a corresponding plan lview showing the bottom surface of the cotton pick sack illustrated in Fig. l;
Fig. 3 is an enlarged fragmentary sectional detail taken substantially on the line 3 3 in Fig. 2;
Fig. 4 is an enlarged fragmentary detail taken substantially on the line 4-4 in Fig. 2; and
Fig. 5 is a fragmentary plan view showing the form of tubular web from which the cotton pick sack illustrated in Figs. 1 and 2 is formed.
Referring now in detail to the drawings, the embodiment of the present invention shown in Figs. 1 and 2 comprises a cotton pick sack having a tubular woven body portion, as indicated generally by the reference numeral 10; the bottom end of which is closed by a relatively narrow, single ply, woven portion 12; and the open top end of which is seamed, as at 14, along that part of the top edge of body portion 10 corresponding to the upper surface of the pick sack when in use, as seen in Fig. 1, while the remainder of the body portion top edge corresponding to the lower face of the pick sack, as seen in Fig. 2, has a bib portion 16 seamed thereat with a shoulder strap 18 installed thereon in the usual manner.
The lower surface of the pick sack, as seen in Fig. 2, also has a wear or drag surface applied directly thereto as indicated at 20; this wear surface 20 being formed by a coating of a thixotropic thermoplastic composition apice as Patent No. 2,893,314, or alternatively including a base coating. Y
Fig. 3 illustrates the tubular woven form of the bod portion 10 with the wear surface 20 applied at one face thereof, and Fig. 4 further illustrates the arrangement of the bottom end closure formed by the single ply portion 12, while Fig. 5 illustrates the manner in which the body portion 10 isr provided in this form from a tubular woven web W, the web W being formed of any usual pick sack material, commonly Osnaburg, andbeing tubular woven according to conventional practice with single ply portions formed transversely therein at a spacing lengthwise of the web corresponding to the length of pick sack desired.
In the form illustrated in Fig. 5, for use in forming the pick sack structure illustrated in Figs. 1 and 2, the Web W has relatively narrow single ply portions 12, of the order of about one inch in width, woven transversely therein to form the previously noted bottom end closure, and these single ply portions 12 are spaced lengthwise in the web W in correspondence with the length of tubular body portion 10 to be provided so that the web W com? prises tubular body portions 10 connected continuously at the single ply portions 12 as illustrated in Fig. 5.
Having provided the web W in this manner, the wear surfaces 20 are then applied at one face thereof at the proper spacing as disclosed by the above noted copendng application Serial No. 685,966 which describes in detail an arrangement of means for such spaced coating of we b material. As illustrated in Fig. 5 the wear surfaces 20 may be spaced to extend lengthwise of the web W in one direction from the single ply portions 12, Vso that the web W becomes a series of tubular body portions 10 arranged kto be separated readily by severing the web W transversely at the edges of the single ply portions 12 opposite the direction in which the wear surfaces 20 extend therefrom. This severing operation can be accomplished by any convenient manner, such as pinking, to provide the tubular body portions 10 in unit form ready to be finished at their top ends by seaming and attachment of a bib portion 16 and shoulder strap 18 thereto as seen in Figs. 1 and 2.
Alternatively, the pattern of the single ply portions 12 can be varied in the web W if desired. For example, the single ply portions 12 might be formed in approxif mately twice the width indicated in Fig. `5, and the lengthwise spacing thereof increased to correspond with twice the length desired for the tubular body portions 10 in forming the web W, and the web W thus formed might have wear surfaces, such as indicated at 20 in Fig. 5, applied in both directions from the wider single ply portions and then be severed midway of the width of, and midway between, these wider single ply portions to obtain the unit tubular body portions 10 therefrom. Additionally, it is possible to provide an integral bib portion, such as is indicated at 16 in Figs. 1 and 2, on the tubular body portion 10` by simply forming single ply portions in the web W having suicient single ply width to afford the necessary material for a bib portion such as 16. If this is done, the tubular body portions as separated from the web are closed at their top, as well as bottom, ends and it is accordingly necessary to slit the body portions adjacent the integral bib portions in order to provide an open top end, and the choice of forming an integral bib portion in this manner, as distinguished from attaching a separate bib portion 16 as illustrated in Figs. 1 and 2, is largely a matter of the relative adaptability to facilities available for the top end finishing operations.
In connection with the wear surfaces 20 provided on Patented Feb. 28, 1961 the tubular body portions 10, as described above, it-
should be noted that a thixotropic thermoplastic composition of the type referred to in the above identified copen'ding applications may be applied to the tubular web W'without any diiculty whatever with fouling of the two ply web portions by bleeding through. Also, by applying the wear surfaces -so that they extend across the single ply bottom closure portions 12 any tendency of these portions to ravel can be eliminated effectively.
, Furthermore, it should also be noted that the wear surfaces 2li rnay be applied directly to the web W in the above indicated manner because the web W is tubular woven according to the present invention so that it does not need to be seamed in forming the sack structure 10A therefrom, as previously mentioned, and consequently does not require turning inside out after seaming in accordance with usual practice. Aviso, due to this absence of seams the inside of the resulting sack structure 10 is entirely smooth so as to be much more easily emptied of picked cotton collected therein than the conventional sack structure in which raw cotton has a pronounced tendency to hang at the inturned seams. Additionally, the tubular woven sack structure 10 has the necessary side edge strength provided therein by the tubular woven selvages and exceptional bottom end strength due to the double density of the single ply portions 12.
The present invention has been described in detail above for purposes of illustration only and is not intended to be limited by this description or otherwise except as defined in the appended claims;
