| 摘要 | An apparatus for forming corner pads utilizing a plurality of plies, each of which is adapted to be folded into a trihedral angle arrangement, wherein the plies are successively fed into juxtaposed relation while adhesive is applied to predetermined surfaces of certain of the plies, and the plies are successively formed into trihedral angle arrangements while being successively placed in contiguous, nesting relationship to secure the nested plies together by the adhesive to maintain the same in a collective trihedral angle arrangement. | ||||||
| 权利要求 | 1. Apparatus for forming a corner pad for protecting the corners of furniture or the like utilizing a plurality of plies, each of which is adapted to be folded into a trihedral angle arrangement with two edges being brought into abutting relation, said apparatus comprising, forming means adapted to receive the plies one at a time and for successively forming the plies into trihedral angle arrangements and for successively placing the formed plies in contiguous, nesting relationship with the attitude of selected plies being varied so that the abutting edges of the plies are out of registry, and means operatively associated with said forming means for applying adhesive to at least one of the contiguous surfaces of adjacent plies to secure the nested plies together to maintain the same in a collective trihedral angle arrangement. 1. Apparatus for forming a corner pad for protecting the corners of furniture or the like utilizing a plurality of plies, each of which is adapted to be folded into a trihedral angle arrangement with two edges being brought into abutting relation, said apparatus comprising, forming means adapted to receive the plies one at a time and for successively forming the plies into trihedral angle arrangements and for successively placing the formed plies in contiguous, nesting relationship with the attitude of selected plies being varied so that the abutting edges of the plies are out of registry, and means operatively associated with said forming means for applying adhesive to at least one of the contiguous surfaces of adjacent plies to secure the nested plies together to maintain the same in a collective trihedral angle arrangement. 2. Apparatus according to claim 1 including feeding means adapted to successively receive the plies and operatively associated with said forming means for feeding the plies one at a time and in succession to said forming means. 3. Apparatus according to claim 2 including storage means positioned in spaced relation to said forming means and operatively associated with said feeding means for storing a stack of the plies and for delivering the same one at a time to said feeding means. 4. Apparatus for forming a corner pad for protecting the corners of furniture or the like utilizing a plurality of generally L-shaped plies, each of which is adapted to be folded into a trihedral angle arrangement in which the edges defining the included angle of the L-shape are brought into abutting relation, said apparatus comprising storage means for storing a stack of the plies in juxtaposed relation, feeding means operatively associated with said storage means for withdrawing the plies one at a time from said storage means and for feeding the same in succession along a predetermined path of travel, means disposed adjacent said feeding means for applying adhesive to predetermined surfaces of certain of the plies as they are being fed by said feeding means, and forming means operatively associated with said feeding means for successively receiving the plies therefrom and for successively forming the plies into trihedral angle arrangements and for successively placing the formed plies in contiguous, nesting relationship so that the adhesive on the Surfaces of the certain plies is brought into contact with the contiguous surfaces of the adjacent plies to secure the plies together and maintain the same in a collective trihedral angle arrangement. 5. Apparatus according to claim 4 whereinn said forming means comprises male forming means adapted to strike each ply at a point adjacent the juncture of the edges defining the included angle of the L-shape, and female forming and nested ply receiving means adapted to engage each ply adjacent its periphery for cooperating with the male forming means in the forming of the ply into the trihedral angle arrangement and for receiving the thusly formed ply therein in contiguous, nesting relationship with previously formed plies. 6. Apparatus according to claim 5 including means mounting said female forming and nested ply receiving means for rotation, and means for rotating said female forming and nested ply receiving means a fraction of a revolution in timed relation to the operation of said male forming means to vary the attitude of at least one ply in each corner pad relative to the other plies so that the abutting edges thereof are out of registry with the abutting edges of the other plies. 7. Apparatus according to claim 6 including means operatively associated with said female forming and nested ply receiving means for withdrawing completed corner pads therefrom. |
