The tube end protector is constructed at least partially out of a resilient material wherein the tube is placed over the tube end protector causing it to deflect until the cardboard tube is properly located on the tube holder wherein the tube end protector resumes its normal configuration and protects the line wound about the cardboard tube from any potential defects at the feeding end of the cardboard tube.
