FIG. 10 is a flow diagram of the preferred embodiment of a method for making foamed sole pads according to this invention; and -
FIGS. 11 to 19 are views showing consecutive steps of the preferred embodiment. - Referring to
FIG. 10 , the preferred embodiment of the method for making foamed sole pads according to this invention includes the steps of: - A) providing a profiled foam blank:
- Referring to
FIGS. 11 , 12, 13, and 14, a profiled foam blank 4 is provided by molding. The profiled foam blank 4 may include oneblank unit 4A or a plurality ofblank units 4A. Eachblank unit 4A has a substantially sole shaped outline and includes front andheel portions surface 41, and a bottom profiledsurface 42 symmetrical to the top profiledsurface 41. In this embodiment, the profiled foam blank 4 includes two interconnectedblank units 4A, and will provide, when divided, two foam blank slices 40 (only one is shown inFIGS. 15 and 17 ), each of which is to be formed into two interconnected sole pads 400 (seeFIGS. 18 and 19 ). If the profiled foam blank 4 includes oneblank unit 4A, the profiled foam blank 4, when divided, will provide two foam blank slices (not shown), each of which will be formed into a singlesole pad 400. - The front and
heel portions blank unit 4A may have different hardnesses. For example, thefront portion 43 is a highly resilient foam blank, and theheel portion 44 is a shock-absorbing foam blank. On the other hand, eachblank unit 4A of the profiled foam, blank 4 may have a first thickness (d1) of 18 mm, and a second thickness (d2) of 12 mm. - The profiled
foam blank 4 may be formed using amold 5 having amold cavity 51 defining the profile of the profiledfoam blank 4 as shown inFIG. 12 , or using amold 5A having amold cavity 51A that differs from themold 5 in that themold 5A does not have curvedinner surface portions 45 of themold 5. The foamblank slice 40 shown inFIG. 17 is obtained from the profiledfoam blank 4 formed by themold 5A. - Referring to
FIG. 16 , if a reinforcingplate 6 is intended to be embedded in the foamed sole pads to be made, it can be positioned at a proper site in themold 5 in this step so as to be embedded in the profiledfoam blank 4 after molding. The reinforcingplate 6 is usually embedded in at least one of the front andheel portions foam blank 4. That is to say, if the reinforcingplate 6 is a shock-absorbing sheet, it is embedded in theheel portion 44 of the profiledfoam blank 4. If the reinforcingplate 6 is a highly resilient reinforcing sheet, it is embedded, in thefront portion 43 of the profiledfoam blank 4. - B) dividing the foam blank:
- Referring to
FIGS. 13 , 15, and 17, the profiledfoam blank 4 is divided along a cutting plane (A) between the top and bottom profiled surfaces 41, 42 to provide two foam, blank slices 40 (only one is shown inFIGS. 15 and 17 ) which are substantially the same in shape and size. Each of the foam blank slices 40 has a cuttingsurface 411, a profiledsurface 414, and afirst side surface 412 and asecond side surface 413 opposite to each other and extending between the cuttingsurface 411 and the profiledsurface 414. Thefirst side surface 412 has a first height (d3), and thesecond side surface 413 has a second height (d4). In this preferred embodiment, the first height (d3) is 9 mm, and the second height (d4) is 6 mm. - C) bonding a fabric layer:
- A
fabric layer 7 is bonded to a surface of each of the foam blank slices 40 by gluing as shown inFIGS. 15 and 17 . If thefabric layer 7 is intended to be bonded to the profiledsurface 414 of each of the foam blank slices 40, the profiledsurface 414 should be roughened before bonding. The roughening step can be conducted via ultraviolet irradiation. Alternatively, if thefabric layer 7 is intended to be bonded to the cuttingsurface 411 of each of the foam blank slices 40, the roughening step is not required. - D) heating:
- Each of the foam blank slices 40 is heated in a baking machine (not shown).
- E) compression molding:
- Referring to
FIGS. 18 and 19 , each of the foam blank slices 40 is compression molded in amold cavity 81 of amold 8 to form foamedsole pads 400. Preferably, themold 8 has a plurality of positioning pins 811 for positioning each of the foam blank slices 40. - F) trimming:
- The foamed
sole pads 400 are trimmed. During and/or after trimming, the foamedsole pads 400 may be separated by cutting. - In view of the aforesaid, the method of this invention has the following advantages:
- 1) The conventional method includes the steps of cutting, slicing, dividing, molding, and trimming, and thus is relatively complicated and produces a great amount of waste material. Specifically, as shown in
FIGS. 8 and 9 , in the conventional method, thesole pads 15 are made by molding the soleblank slice 14 having a square shape. Therefore, a relatively large amount of waste material is produced during the trimming step. In the method of this invention, as shown inFIG. 15 , the foamblank slice 40 having a predetermined profile is prepared, which is molded to form the foamedsole pads 400 as shown inFIG. 19 . The waste material trimmed from thesole pads 400 is reduced significantly as compared to that produced by the conventional method. Furthermore, the method of this invention is simplified and time-saving. Therefore, the production cost can be reduced by the method of this invention. - 2) In the conventional method, the sole
blank slices 14 are formed from the foamblank sheet 10 via trimming the foamblank sheet 10, cutting thefoam semi-product 11, bonding the fabric layers 2, dividing thefoam products 12, and cutting each of thesole blanks 13. However, in the method of this invention, the profiledfoam blank 4 can be provided by molding, and is then processed simply via dividing thefoam blank 4 to form the foam blank slices 40 and bonding thefabric layer 7 to the foam blank slices 40. Therefore, the method of this invention is simplified, time-saving, and produces less waste material. - 3) In the conventional method, if a thickness of a specific area of the foamed sole pads is intended to be increased, an additional foam blank is required to be glued on the specific area. However, in the method of this invention, any specific shape of the foamed sole pads can be obtained using a mold, for instance, the
mold 5 having themold cavity 51 with a specific profile to prepare the profiledfoam blank 4 according to the specific requirement. Therefore, as compared to the conventional method, the method of this invention is relatively efficient and flexible. - 4) Furthermore, in the conventional method, if a highly resilient reinforcing sheet or a shock-absorbing sheet is intended to be included in the foamed sole pads, each of the sole
blank slices 14 before being bonded with thefabric layer 2 should be formed into a sole blank (not shown), which is then embedded with the reinforcing plate, and subsequently bonded with thefabric layer 2. However, in the method of this invention, as shown inFIG. 16 , a reinforcingplate 6, such as the highly resilient reinforcing sheet or the shock-absorbing sheet, can be positioned in themold cavity 51 of themold 5 when preparing the profiledfoam blank 4. Therefore, when compared to the conventional method, the method of this invention is relatively flexible for the specific requirements of the foamed sole pads. - While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
