Strap pulling device and pulling method

A strap pulling device, comprising:

• a cutter mechanism;
• a first strap pulling mechanism;
• and
• a second strap pulling mechanism, wherein
• the first strap pulling mechanism clamps a free end of a strap and pulls the strap from a pulling position to a transfer position, and the second strap pulling mechanism moves to the pulling position to clamp the strap, such that the first strap pulling mechanism and the second strap pulling mechanism simultaneously clamp the strap, wherein the pulling position is located upstream of a cutting position and the transfer position is located downstream of the cutting position;
• and
• wherein the cutter mechanism cuts the strap at the cutting position to acquire a strap segment having a predetermined length.

A strap pulling method, characterized by comprising:

• controlling a first strap pulling mechanism to clamp a strap at a pulling position located upstream of a cutting position, and pull the clamped strap to a transfer position located downstream of the cutting position;
• controlling a second strap pulling mechanism to clamp the strap at the pulling position when the first strap pulling mechanism pulls the strap to the transfer position;
• controlling a cutter mechanism to cut the strap at the cutting position to acquire a strap segment having a predetermined length;
• controlling the second strap pulling mechanism to pull the clamped strap to the transfer position;
• and
• controlling the first strap pulling mechanism to clamp the strap at the pulling position and execute the pulling of a next section of the strap when the second strap pulling mechanism pulls the strap to the transfer position.
