Apparatus for forming edgewise wound cores

Apparatus for forming edgewise wound cores from a continuous strip of generally thin ferromagnetic material, the apparatus comprising:

• means operable generally for deforming the continuous strip generally edgewise thereof into a plurality of generally helical convolutions;
• means associated with said deforming means for receiving the helical convolutions and including a set of means movable between protracted and retracted positions and operable generally in the protracted position thereof for supporting the helical convolutions generally in an axial stack thereof on said receiving means, and means movable between an at-rest position and a camming position for camming in engagement with said supporting means, respectively;
• and
• means for accepting the axial stack of the helical convolutions from said receiving means and movable between a position displaced therefrom and another position at least adjacent thereto, said accepting means including means operable generally upon the movement of said accepting means from the displaced position toward the another position thereof to abut and move said camming means from the at-rest position toward the camming position thereof in camming engagement with said supporting means thereby to move said supporting means from the protracted positions toward the retracted positions thereof so as to disassociate said supporting means from the axial stack of the helical convolutions on said receiving means, respectively, and means for supporting engagement with the axial stack of the helical convolutions upon the transfer thereof from said receiving means to said accepting means when said supporting means are moved into the retracted positions thereof, respectively.

Apparatus for continuously forming edgewise wound cores from a continuous strip of generally thin ferromagnetic material, the apparatus comprising:

• means operable generally for deforming the continuous strip into a plurality of generally helical convolutions thereof;
• means arranged for receiving the helical convolutions from said deforming means and for accumulating the helical convolutions generally in an axial stack thereof, said receiving and accumulating means including a pair of relatively movable means associated in an engaged position and operable for separation toward a displaced position, and means on one of said relatively movable means for supporting the axial stack of the helical convolutions received on said receiving and accumulating means;
• means arranged at least in part between said deforming means and said receiving and accumulating means and operable generally for severing a respective one of the helical convolutions at least generally when the axial stack of the helical convolutions on said supporting means attains a preselected axial stack height thereby to define one of the edgewise wound cores;
• means associated with said one relatively movable means and operable generally for separating it to the position displaced from the other of said relatively movable means upon the severance of the respective one helical convolution;
• and
• said other relatively movable means including a set of means operable generally from retracted positions toward protracted positions for intercepting and supporting in another generally axial stack on said other relatively movable means at least some of the helical convolutions following the respective one helical convolution upon the severance thereof, and means associated in abutment with said one relatively movable means at least when said relatively movable means are in the engaged position thereof and operable generally in response to the separation of said one relatively movable means to the position displaced from said other relatively movable means for controlling the operation of said intercepting and supporting means from the retracted postions toward the protracted positions thereof, respectively.

Apparatus for forming edgewise wound cores from a continuous strip of generally thin ferromagnetic material, the apparatus comprising:

• means operable generally for deforming the continuous strip into a plurality of generally helical convolutions thereof;
• means associated with said deforming means for receiving therefrom the helical convolutions and including a set of means movable between retracted and protracted positions and operable generally in the protracted positions thereof the supporting in a generally axial stack at least some of the helical convolutions received on said receiving means, and means movable between an at-rest position and another position and operable generally in the another position for camming said supporting means toward the retracted positions thereof so as to disassociate said supporting means from the axial stack of the at least some helical convolutions received on said receiving means, respectively;
• and
• means movable from a displaced position to another position at least adjacent said receiving means for accepting therefrom at least the axial stack of the at least some helical convolutions, said accepting means including means for engaging and moving said camming means from the at-rest position toward the another position thereof at least when said accepting means is in its another position thereby to cam said supporting means toward the retracted positions thereof dissassociated from the axial stack of the at least some helical convolutions received on said receiving means and effect the transfer therefrom of the axial stack of the at least some helical convolutions to said accepting means, respectively.
