Abstract
A thin-web frame feeding device for intermittently feeding a thin-web frame at a predetermined pitch along a guide rail has first and second shafts supported by bearing stands for synchronized axial sliding motion in the same direction and for rotation in opposite directions. The first and second shafts are provided with feeding claws rotatable in accordance with the rotation of the shafts into and out of positions where spontaneous portions of the thin-web frame are clamped. The feeding claws are axially moved in accordance with the axial sliding movement of the shafts to feed the thin-web frame.
Claims8
A device for feeding a thin-web frame at a predetermined pitch along a guide rail comprising:
- at least two bearing stands;
- first and second generally parallel shafts axially slidably and rotatably carried by said bearing stands;
- at least one first feeding claw and at least one second feeding claw fixed to said first and second shafts, respectively, extending substantially orthogonally from said respective shafts and substantially aligned with each other, said first and second feeding claws cooperating with each other to clamp said thin-web frame therebetween for feeding said thin-web frame;
- a coupling plate rotatably holding said first and second shafts for synchronized axial sliding of said first and second shafts;
- and
- rotational drive means for rotating said first and second shafts simultaneously in opposite directions whereby said first and second feeding claws are axially moved by said coupling plate and are rotatingly moved between open and closed positions by said rotational drive means.
An apparatus comprising:
- a die apparatus including a lower die member having a die, an upper die member having a punch, and guide posts fixed to and supported by said lower die member for slidingly guiding said upper die member in alignment with said lower die member during movement of said upper die member towards and away from said lower die member;
- a guide rail extending between said die and said punch;
- a feeding device mounted on said lower die member including feeding claws for clamping a thin-web frame intermittently at a predetermined pitch along said guide rail, said feeding device including:
- (a) at least two bearings,
- (b) first and second generally parallel shafts axially slidably and rotatably supported by said bearings,
- (c) at least one first feeding claw and at least one second feeding claw extending in a first direction and respectively connected to and projecting orthogonally from said first and second shafts towards said die and said punch and substantially in alignment with each other for cooperatingly clamping and feeding said thin-web frame,
- (d) a coupling plate rotatably supporting said first and second shafts for synchronized axial sliding of said first and second shafts,
- (e) at least one arm fixed to at least one of said first and second shafts and having a first end extending substantially in the first direction and a second end extending in a direction opposite to the first direction, and
- (f) first and second gears mounted on said first and second shafts, respectively, and meshing with each other for transmitting rotation of one of said first and second shafts to the other of said first and second shafts;
- and
- external drive means spaced from said die apparatus and disconnectably drivingly connected to said feeding device for driving said feeding device.
