FIELD: packing industry. ^ SUBSTANCE: clamp is manufactured of material having shape of tape or wire. Corrugated profile with the first and second topes following each other is stamped. The first top creates clamp base and accordingly edges of U-shaped bent shelf of clamp adjacent on both sides to the first top. The second top, versus U-shaped form, creates ends of shelves bent outside, to which two adjacent clamps adjoin with the possibility of separation. Besides material of clamp having shape of tape or wire is pierced inside versus U-shaped form, so that convexity of material is formed on internal side of shelf. ^ EFFECT: improved clamping force of clamp, increased resistance to clamp slipping. ^ 13 cl, 4 dwg |
