Abstract
A linking machine in which three stepper motors are provided which adjust the opening width between the two rails of a conveyor, the height of the rails of the conveyor, and the vertical position of an edge trimmer with respect to the plane of transport of the socks. The stepper motors are actuated by drivers from a microprocessor which, in its turn, can be controlled via a keyboard. The keyboard is connected with a display which displays the data of each individual adjustment as well as the data of the program selected.
Claims3
A linking machine for socks, comprising:
- a stand;
- a vertical wall fixed to the stand;
- a horizontal support bracket connected to the vertical wall so as to be vertically moveable;
- an edge trimmer mounted to the stand, said edge trimmer being vertically adjustable;
- sewing heads mounted to the stand;
- first conveyor means for transporting the socks to the edge trimmer, the first conveyor means including a stationary rail and a moveable rail mounted to the support bracket and wherein a slot is defined between the rails;
- second conveyor means including chains for transporting the socks from the edge trimmer to the sewing heads;
- first electric stepper motor means for moving the moveable rail;
- second electric stepper motor means for moving the support brackets;
- third electric stepper motor means for adjusting the edge trimmer relative to the chains;
- and
- programmable electronic control means for controlling the first, second and third electric stepper motor means, the control means including control keys which are operative to selectively place the first, second and third electric stepper motor means in forward and reverse operation, the control means being operative to store and call up parameters that define a mutual position of the rails, a vertical position of the support bracket, and a vertical position of the edge trimmer relative to the chains.
