Design Of Cross Tongue Type Shallow Enclosure Shoes

1. finished product design plan

As shown in figure 2-2-3, if you do not look at the shallow bar, this is a cross tongue shoe.

With the shallow surround strip, it will form a cross tongue type shallow shoe.

If you do not look at the tongue, the outer part is roughly the same as the inner ear type shallow shoe.

 

The design requirements of the cross arm are invariable, and the 3mm of the back midline should be higher.

The bottom foot of the last load is pressed underneath the underside of the fence, because the sewing process is more wrapped around the hand, then it is replaced with the surrounding strip so that the cross arm line can be completed after the car is finished.

The shoe covers of this type of shoes are decorated with the fake wire technology.

The position of the false line is similar to that of the usual enclosure, and the method is to evenly collect 10mm around the shallow strip.

2. structure design drawing

The structure design of the tongue type shallow enclosure shoe is shown in figure 2-2-4.

 

(1) first design the tongue of the shoe and design the tongue from the point of V, the length is near the 1 / 2VE and the width is still on the OQ line.

Design the straight back Gang, with the difference between inside and outside.

Design the rear package and outline.

Connect the back line.

(2) design the shoe cover and the fence strip, use the two arc intersection point to find the J'point, connect the back midline J'V.

From the point of J', draw the outer outline of the shoe cover with the copy board on the straight line in the back, then connect it to the straight line of the surround strip, and the ending point is O'.

From the point of J', draw the outer outline of the fence with the replica board on the back curve, and go straight to the O' point.

Make the difference between the inside and outside of the shoe cover and the enclosure.

The front line of the fence is connected with the AJ'line as the center line of the girth.

The vertical line of the center line is corrected along the circular line of the fence, and the amount of loss is supplemented by the bottom tension.

As shown in the shadow.

Finally, the contour of the bottom rib and the difference between inside and outside are designed.

Because the surround bar of shallow surround shoes is long and the material is not strict, it will cause more waste and waste on materials.

To this end, in the decoration of the shoes, usually use the method of segmentation, design smaller parts, can insert inserts to reduce waste, see figure 2-2-5.
