Danieli & C. Officine Meccaniche has been granted a patent for a binding machine that includes a feeding and tensioning device, a joining device, a gripping arrangement, and an electronic control device. The machine is designed to feed and tighten a binding element around objects, form a joint between two sections of the element, and subject the joint to a tensile test to check its strength. The gripping arrangement keeps the first binding element section secured during the test. GlobalData’s report on Danieli & C.

A recently granted patent (Publication Number: US11643232B2) describes a binding machine that is capable of forming a closed loop of an elongated binding element, such as a wire or strap, and testing the strength of the joint formed in the loop. The machine includes a feeding and tensioning device that feeds the binding element in a loop around a space designed to hold objects to be bound. After the loop is formed, a gripping arrangement locks the leading end of the binding element in place. A joining device, which can be a welding device such as a laser welding device, forms a joint between the leading end and the trailing end of the binding element to create a closed loop.

The machine also features an electronic control device that controls the feeding and tensioning device to exert a tensile force on the binding element after the joint is formed. This force subjects the joint to a tensile test, allowing the strength of the joint to be checked. During the tensile test, the gripping arrangement keeps the leading end of the binding element secured in a fixed position by engaging a part of the binding element located between the joint and the leading end.

The gripping arrangement includes a support member that supports the leading and trailing ends of the binding element during the formation of the joint. A recess is provided in the upper support surface of the support member, and a pressing element, controlled by an actuating device, can be received in the recess. When the pressing element and the support member are moved in relation to each other, they form a bulge on the part of the binding element located between them.

Additionally, the machine includes a squeezing device that squeezes the trailing end of the binding element against the leading end, with the trailing end overlapping the leading end. The squeezing device comprises a squeezing member that cooperates with the support member. The squeezing member can be moved between a retracted position and an advanced position to squeeze the binding element sections together. The electronic control device controls the squeezing device to keep the squeezing member in the retracted position during the formation of the joint and in the advanced position during the execution of the tensile test.

Overall, this patented binding machine offers a comprehensive solution for forming and testing the strength of closed loops made from binding elements, providing improved efficiency and reliability in the binding process.
