FAQ
Q1: How are paper tubes wound?
A: Paper tubes and cores are wound from plies of paper under controlled tension with adhesive, onto a rotating mandrel.
Q2: What gives a core its strength?
A: Controlled ply tension and uniform adhesive bond the plies, giving the core its crush and telescope resistance.
Q3: Why does diameter matter?
A: Accurate diameter ensures the core runs true and fits winding equipment.
