Abstract
An apparatus and method for securing a tape loop hanger at the gathered end of a stuffed or unstuffed casing using a substantially U-shaped clip. Specifically the U-shaped clip forces a preformed tape loop hanger into contact with a gathered end portion of a casing whereupon the two opposed legs of the clip are deformed to encircle the gathered casing and the tape loop hanger with sufficient pressure so as to crimp and anchor the tape loop hanger between the legs of the clip so as to secure the tape loop hanger to the gathered end of the casing.
Claims12
An apparatus for securing a tape loop hanger at the gathered end portion of a casing using a substantially U-shaped clip member comprising:
- a. means for continuously and successively supplying a predetermined length of tape from a supply source;
- b. means for forming a loop hanger in each of said predetermined lengths of tape and supporting each of said tape loop hangers so formed in relative alignment with a gathered end portion of a casing;
- c. means for continuously and successively supplying a substantially U-shaped clip in relative alignment with the tape loop hanger and the gathered end portion of the casing, said clip comprising a pair of opposed legs and a crown connecting the corresponding end of said legs;
- and
- d. means for first advancing and projecting said clip onto and about said tape loop hanger, and then advancing said clip and said tape loop hanger into contact with said gathered end portion of the casing and thereafter deforming the legs of said clip to encircle said tape loop hanger and said gathered end portion of the casing so that said tape looper hanger is secured to the gathered end of said casing.
A method for securing a tape loop hanger at the gathered end of a casing using a substantially U-shaped clip comprising the steps of:
- a. gathering an end portion of a casing;
- b. forming a loop hanger having two extended free ends from a predetermined length of tape and positioning said tape loop hanger in substantial alignment with said gathered end portion of said casing;
- c. advancing a substantially U-shaped clip having a crown member connecting corresponding ends of two opposed legs into contact with said tape loop hanger so as to initially position said tape loop hanger adjacent the crown member between the legs of said clip;
- d. advancing the clip and tape loop hanger into contact with the gathered end portion of said casing;
- and
- e. deforming the legs of said clip to encircle the tape loop hanger and the gathered end portion of the casing so as to secure said tape loop hanger to the gathered end portion of the casing via said clip.
A method for securing a tape loop hanger at the gathered end of a casing using a substantially U-shaped clip comprising the steps of:
- a. gathering an end portion of a casing;
- b. forming an upstanding loop hanger having two extended free ends from a predetermined length of tape and positioning said upstanding tape loop hanger in substantial alignment with said gathered end portion of said casing;
- c. advancing a substantially U-shaped clip having a crown member connecting corresponding ends of two opposed legs into contact with the upstanding tape loop hanger such that the crown of the clip contacts the edge of the upstanding tape loop hanger and forces it to rotate into substantial parallel alignment with said crown where the tape loop hanger having a width larger than the length of the crown becomes initially crimped thereat;
- d. advancing the clip and tape loop hanger into contact with the gathered end portion of said casing;
- and
- e. deforming the legs of said clip to encircle the tape loop hanger and the gathered end portion of the casing so as to secure said tape loop hanger to the gathered end portion of the casing.
