Abstract
This invention relates to a device for fixing fasteners to the flaps of corrugated cardboard boxes for sealing the flaps. With the fastener placed across the adjoining edges of at least two flaps, piercing nails in the form of a cow horn and attached to a pair of turnable pieces on the fastener are driven into the flaps by the device. The device is characterized in that two reciprocally movable sliders (12, 13) move to drive a cutting blade (17), causing the blade to separate a fastener from other fasteners, and subsequently drive pivotal members (29a, 29b) to depress the turnable pieces on the fastener, driving the piercing nails into the flaps. Fasteners can be fixed in place easily and reliably.
Claims8
A device for applying to an article such as a packaging box a fastener having a flat main plate and a pair of turnable pieces hingedly connected to the main plate and each having a piercing nail, the device comprising:
- a framework;
- a first slider reciprocably carried by the framework and having an outer end provided with a cutting blade adapted to cut the fastener from a strip of connected fasteners;
- a second slider reciprocably carried by the framework, a pair of pivotable members carried by the framework and adapted to engage the pair of turnable pieces of a fastener, and means for pivoting the pair of members in response to reciprocating movement of the second slider;
- and means for driving the first and the second sliders one at a time in succession on fastener cutting and applying movements, respectively, whereby a fastener is cut from the strip of fasteners by the cutting blade of the first slider and the turnable pieces of the cut fastener are thereafter engaged and moved by the pair of pivotable members to force the piercing nails into the article.
