Bonding of elastomeric substrate under stretched conditions

A method of bonding material in a process system for producing a bonded product, the method comprising the steps of:

• providing a first material and a second material into a bonder system;
• wherein the first and second materials have a first speed upon entering the bonder system and a second, faster speed after progressing along the bonder system, the difference in speed generating a speed differential, wherein the speed differential imparts a stretched state to the first and second material;
• introducing the first material and the second material into a nip disposed upstream of a bonder;
• passing the first and second material through the nip wherein the nip imparts a substantially equal stretched state simultaneously to the at least first and second quantities of material;
• and
• bonding the stretched first and second material together with a bonder of the bonder system wherein the bonder does not pull the material.

A method of bonding material in a process system for producing a bonded product, the method comprising the steps of:

• providing a first material and a second material to a bonder system;
• progressing the first and second material toward a pressure bonder;
• introducing the first material and the second material into a nip disposed upstream of the pressure bonder, wherein the first and second materials have a first speed upon entering the nip and a second, faster speed after exiting the nip, the difference in speed generating a speed differential, wherein the speed differential imparts a stretched state to the first and second material;
• passing the first and second material through the nip wherein the nip imparts a substantially equal stretched state simultaneously to the at least first and second quantities of material;
• and
• bonding the stretched first and second material together with the pressure bonder wherein the bonder does not pull the material.
