Embodiment

In conjunction with the accompanying drawings the present invention is described in further detail below by embodiment.

In the production that stretches, operation just can be finished because finished product also needs to cut edge, need through the side cut operation the unnecessary material removal of oral area, thereby, the shape of tinsel, size do not have strict requirement, it is just passable to leave suitable surplus, therefore, can adopt metal tape and the manufacture method thereof with tinsel of the present invention.

As shown in Figures 2 and 3, present embodiment metal tape 1 comprises row's tinsel 11, each tinsel 11 coaxial line A, and each tinsel 11 connects on this axial direction in turn.Have two spaces 12 between two adjacent tinsels 11, these two spaces 12 are about this axis A symmetry, and on vertical and direction away from this axis A, each space 12 increases gradually.

Two adjacent tinsels 11 can be about first axle B symmetry, and each first axle of metal tape is parallel.For each space 12, it all can be divided into top 13 and bottom 14 by this first axle, and top 13 and bottom 14 are about this first axle B symmetry.Each space can also can be positive isosceles trapezoid or equilateral triangle for little tubaeform of the outer imperial palace of bore, certainly, also can be the outer little shape of imperial palace of other bore.

When tinsel 11 has the shape of arc for circle, subcircular, ellipse, nearly ellipse etc., each space can be for tubaeform, this subcircular refers to be made up of and the shape of the similar circle of global shape arc, straightway, and this nearly ellipse refers to be made up of and the similar oval in shape of global shape arc, straightway.When the attachment portion of two adjacent tinsels 11 was straightway, the space can be equilateral triangle, positive isosceles trapezoid or tubaeform.

For this metal tape, when follow-up needs process tinsel, can obtain needed tinsel directly in the processing of the joint of two metal sheets (along first axle B processing).

As shown in Figure 4, it is second embodiment of tinsel, the main distinction of this mode of execution and first embodiment is: each tinsel 11 comprises middle part 15 and is positioned at the sidepiece 16 of these both sides, middle part, this middle part 15 is square, as square or rectangular, this sidepiece 16 is positive isosceles trapezoid, and the space 12 between two adjacent tinsels 11 also is positive isosceles trapezoid, and this positive isosceles trapezoid refers to that the base angle is 60 degree and can makes sidepiece 16 turn over the isosceles trapezoid of coincideing with space 12 after the turnback.This middle part 15 can be about the axis A symmetry of tinsel, and two sidepieces 16 also can be about this axis A symmetry.When directly processing this metal tape, reduced difficulty of processing by raw band.In addition, also can process the positioning hole 17 of being convenient to accurately send band on this metal tape.

As shown in Figure 5, a kind of processing method of metal tape, it is directly processing and the metal tape that obtains tinsel or have tinsel on raw band 2.When direct processing obtains tinsel, at least two rows hole consistent with tinsel arranged on the raw band that stays (being waste material), and each hole of i row is between i+1 row's two holes.

When direct processing obtains having many rows metal tape of tinsel, the raw band 2 that stays comprises at least two row's metal tapes 1, each metal tape 1 all has at least two tinsels 11, and the sidepiece 16 of each tinsel of i row metal tape is promptly filled in the space of this two adjacent tinsel between the sidepiece of two adjacent tinsels of i+1 row metal tape.The distribution of the tinsel of each metal tape, shape, structure etc. can be as described above.
