Apparatus and method for molding brassiere cups
View Patent ↗An apparatus and method are provided for molding breast cups in a seamless circularly-knitted brassiere having a breast-covering portion and a torso encircling band, the apparatus comprising a base, a rear wall extending upwardly from the base, an upper mold plate extending outwardly and substantially horizontally from the rear wall, the upper plate having a pair of spaced openings formed therethrough, the openings spaced and dimensioned to correspond to a pair of breast cups, and a plate intermediate to the base and the upper mold plate, and being vertically moveable between a first, upper position and a second, lower position for securing a brassiere blank in position against the upper plate for the molding of breast cups therein.
1. An apparatus for molding breast cups in a seamless, circularly-knitted brassiere having a breast-covering portion and a torso encircling portion, the apparatus comprising:
a base;
a rear wall extending upwardly from the base;
an upper mold plate extending outwardly and substantially horizontally from the rear wall, the upper mold plate having a pair of spaced openings formed therethrough, the openings spaced and dimensioned to correspond to a pair of breast cups;
an intermediate plate between the base and the upper mold plate, and being vertically moveable between a first, upper position and a second, lower position for securing a seamless brassiere in position against the upper mold plate for the molding of breast cups therein; and
a projecting element extending upwardly from a top surface of the intermediate plate through the rear wall, and upwardly beyond an upper surface of the upper mold plate, the projecting element configured to engage a lower surface of a male mold plate, wherein when the male mold plate is lowered and engages the upper mold plate, downward movement of the projecting element moves the intermediate plate to the second, lower position.
2. The apparatus of claim 1 , wherein the upper mold plate is interchangeably removable for varying dimensions and spacing of the openings.
3. The apparatus of claim 2 , wherein the upper mold plate is interchangeably removable from the rear wall with threaded fasteners.
4. The apparatus of claim 1 , further comprising a lower bar positioned between the base and the rear wall, wherein the lower bar is for limiting downward movement of the intermediate plate.
5. The apparatus of claim 1 , further comprising an upper bar attached between the rear wall and the upper mold plate.
6. The apparatus of claim 1 , wherein the intermediate plate comprises a pair of spaced apart outwardly extending arms, the arms extending perpendicular to the rear wall, wherein the arms are configured for pulling taut the torso encircling portion when the intermediate plate is moved vertically downward.
7. The apparatus of claim 1 , wherein the intermediate plate extends through a slot in the rear wall, the slot having a height and a width.
8. The apparatus of claim 7 , further comprising at least one post extending the height of the slot and through the intermediate plate, wherein the intermediate plate is vertically movable along the at least one post.
9. The apparatus of claim 8 , wherein the at least one post further comprises a spring element, wherein the spring element is for biasing the intermediate plate to the first, upper position.
10. The apparatus of claim 9 , wherein the spring element comprises a compression spring having a spring constant of between about 10 lb and 25 lb.
11. A method of molding breast cups in a seamless circularly-knitted brassiere having a breast-covering portion and a torso encircling portion, the method comprising:
(a) placing the breast-covering portion of a substantially completed seamless brassiere on an upper surface of an upper mold plate;
(b) aligning breast cup areas of the brassiere with a corresponding pair of mold openings in the upper mold plate;
(c) wrapping the torso encircling portion of the brassiere around a bottom surface of a vertically moveable lower plate;
(d) causing the lower plate to move vertically downward relative to the upper mold plate, wherein the torso encircling portion of the brassiere and the breast covering portion are pulled taut; and
(e) lowering a male mold portion downwardly to engage the upper mold plate, wherein male mold elements move through the openings in the upper mold plate to stretch and permanently mold a pair of breast cups in the brassiere.
12. The method of claim 11 , wherein lowering the male mold portion engages a projecting element extending upwardly from the lower plate so that the lower plate moves vertically downward.
13. The method of claim 11 , further comprising raising the male mold portion after molding the pair of breast cups, wherein raising the male mold portion biases the lower plate upwardly.
