The present invention relates to a bias type supply device adapted to supply a bias tape folded in two in a framing work with use of the bias tape which is employed as a hem for making dress and the like.
It is in general heretofore known in framing a fabric with a sewing machine to tentatively fasten one end of a bias tape to an edge of the fabric and finally fix it thereon while folding it over so as to cover a rear edge thereof.
Such prior framing operation however suffers from a drawback: The operation must be repeated twice, requiring a longer time therefor.
To solve such a problem, there is conventionally known a bias tape supply device as described below.
Referring to FIG. 7, a tape dispensing device as shown, which includes a molded structure bonded on a sheet of paper 4, which is provided with an integrally formed housing part 2 and a guide part 3 for a bias tape 1 comprising a thin plastic film. The bias tape 1 is housed in a housing part 2 and is commerically available in this form. The guide 3 is gradually reduced in height toward the tape delivery outlet and is adapted to cause the bias tape 1 to be bent down while being folded double upon delivery from the tip of the guide part 3. The guide part 3 has a slit 5 formed therein for passing an edge of the fabric therethrough when sewing it with a sewing machine.
The back side of the sheet of paper 4 is coated with a bonding agent and bonded on a prescribed portion of the sewing machine at a convenient location for framing the fabric.
Such a prior art bias tape supply device as described is a disposable type, and thus expensive.
The bias tape 1 in the prior art device is bonded and separated several times until it is utilized to the fullest, so that the bonding agent 6 may be damaged, resulting in insufficient bonding.
The tip of the guide part 3 is simply rectangle-shaped, so that the bias tape folded double is rotated in the guide part and the shape of the delivered bias tape is unsettled. Accordingly, the framing operation takes much time.
In addition, the bias tape comprises paper and a thin plastic film, so that it is fragile and difficult to be stored for a long time.
In view of the drawbacks with the conventional bias tape supply device, it is an object to provide a bias tape supply device adapted to permit a delivered bias tape to remain folded over at all times
To achieve the above object, a bias tape supply device according to the present invention has a synthetic resin circular housing part for housing a bias tape and a synthetic resin guide part for delivering the bias tape from the housing part.
The housing part comprises a top circular wall, a bottom circular wall, a cylindrical circumferential wall, and a magnet fixed outside the bottom circular wall. The circumferential wall has a slit formed therein for passing a bias tape through it, at which a base end of the guide part is located.
The guide part comprises an upper wall, a lower wall, and first and second side walls provided on both sides of the foregoing upper and lower walls. The guide part is adapted to extend from the circumferential wall of the housing part to the outside thereof and be substantially L-shaped, while the foregoing side walls gradually decrease in height from the base end to the tip of the guide part. At the tip portion of the guide part, the first side wall of the guide part located in the vicinity of the housing part is adapted to be low in height, while the second side wall is adapted to be higher than the first one, thereby giving the tip portion of the guide part a substantially triangle-shaped cross-section. Two projections are provided on the tip of the second side wall extending generally toward the firstside wall, and a slit is formed in the second side wall between the two projections.
The bottom circular wall of the housing part and the lower wall of the guide part are kept horizontal, and parallel to each other and are integrally assembled. Likewise, the top circular wall of the housing part and the upper wall, and the first and second side walls of the guide part are integrally constructed, while the circumferential wall of the housing part is also formed integrally with the top circular wall, or, alternatively, the bottom circular wall of the housing part.
The circumferential wall of the housing part is covered with the top circular wall or the bottom circular wall of the housing part, and fixed.

FIG. 6 is a plan view illustrating the bottom cover side as viewed from the back thereof; and
FIG. 7 is a perspective view illustrating a prior art bias tape supply deive.
In making a dress with a fabric, some damage may result if an edge of the dress is left as it is, so that it is beneficial that a bias tape be folded in two for holding the edge from both sides thereof and fixing the edge with thread. Namely, provided the bias tape is supplied being previously folded in two, the dress edge can be fixed with thread only at a time and thus be very convenient.
The bias tape supply device according to the present invention is adapted to be freely mounted and demounted in a prescribed position on a sewing machine and to be capable of supplying a bias tape in a folded over state.
Referring to FIGS. 1 to 3, the bias tape supply device comprises a synthetic resin circular housing part 11 for housing a bias tape T (shown in FIG. 5) and a synthetic resin guide part 12 for delivering the bias tape T from the housing part 11.
The housing part 11 has a top circular wall 13, a bottom circular wall 14, a cylindrical circumferential wall 15, and a magnet 16 fixed outside the bottom circular wall 14.
A slit 17 is formed in the circumferential wall 15 for passing the bias tape T therethrough, and a base end of the guide part 12 is positioned at the slit 17.
The guide part 12 comprises an upper wall 18, a lower wall 19, and a first and second side walls 20, 21 provided on both sides of the upper and lower walls, which extend as a whole from the circumferential wall 15 of the housing part 11 to a point distant therefrom forming a substantially L-shaped guide. The first side wall 20 and the second side wall 21 of the guide part 12 gradually decrease in height from the base to the tip of the guide part 12, and at the tip portion of the guide part, the first side wall 20 located near the housing part 11 is adapted to be low in height while the second side wall 12 is adapted to be higher than the former, and the tip of the guide part is substantially triangle-shaped in cross-section. Two inwardly directed projections 22 are provided on the tip of the second side wall 21, and a slit 23 is formed in the second side wall 21 between the two projections 22. The slit 23 is not needed to be provided over the whole length of the guide part 12, and it is sufficient to be formed in at least at the L-shaped top end of the guide part.
The bias tape supply device according to the present invention is divided into an upper and a lower part and the parts are joined with each other, so that the guide part 12 is also formed in upper and lower parts. Accordingly, it is desired to employ the slit 23 as a joint between the upper and lower portions of the device.
The bottom circular wall 14 of the housing part 11 and the lower wall 19 of the guide part 12 are kept horizontal and integrally formed with each other, and likewise the lower wall 19 of the guide part 12 and the lower side of the slit 23 notched in the second side wall 21 are integrally formed to provide a lower cover side C. The top circular wall 13 of the housing part 11, and the upper wall 18, the first side wall 20 and the part of the second side wall 21 above the slit 23 are integrally formed, while the circumferential wall 15 of the housing part 11 is formed integrally with the top circular wall 13 in the present embodiment to provide a vessel side V. In addition, the circumferential wall 15 may be formed to be integral with the bottom circular wall 14 of the housing part 11.
A circumferential short upstanding part 24 is provided on the bottom circular wall 14 of the housing part 11. The upstanding part 24 is fitted in a recessed annular surface 25 provided in the circumferential wall 15, whereby the vessel side V is covered with the cover side C and fixed in place.
Operation of the bias tape supply device described above is as follows:
Referring to FIGS. 4 and 5, the bias tape T is housed in the vessel side V, and part of the tape is allowed to pass through the slit 17 and the guide part 12, and exits from the tip of the guide part as shown by T1. The bias tape T is folded over in the vicinity of the tip of the guide part 12. After the vessel side V is covered with the cover side C, the ends of the bias tape T1 folded over are inserted into the space between the projections 22 on the tip of the guide part 12 and the upper wall 18 and lower wall 19. The bias tape supply device is fixed on a prescribed portion of a sewing machine with the magnet 16 (shown in FIG. 6), and the bias tape T can be successively delivered with the progress of the biassing operation.
With the arrangement of the present invention, the lower cover side and the vessel side are made detachable. Accordingly, when a bias tape is used up, a new bias tape can be inserted in the vessel, and the device can be reused any number of times, and be of low-cost because the tape supply device is not employed disposably.
The bias tape supply device is fixed at a prescribed position on a sewing machine by a magnet. Consequently, the ability of the device to stay fixed remains unchanged even if it is mounted or demounted many times.
The projections provided on the tip of the guide part allow both ends of the bias tape to be held and positioned. Accordingly, the bias tape can be delivered without fail while folded in two, simplifying and facilitating the biassing operation by a sewing machine.
In addition, the guide part is made of a thick synthetic resin material. Accordingly, the bias tape supply device is not damaged and durable for long-term application thereof.
