An apparatus (2) comprises: first clamp means (30) for indexing sheet material (6, 10) through its own forming means (24, 26, 28), further clamp means (52; 54) for advancing said sheet material (6; 10) towards said first clamp means (30) synchronously; the first clamp means (30) and/or the further c
An apparatus (2) comprises: first clamp means (30) for indexing sheet material (6, 10) through its own forming means (24, 26, 28), further clamp means (52; 54) for advancing said sheet material (6; 10) towards said first clamp means (30) synchronously; the first clamp means (30) and/or the further clamp means (52; 54) are coupled to electronic control means and are mechanically disconnected to each other; a method comprises: indexing sheet material (6, 10) through its own forming means (24, 26, 28) by acting on a region of said sheet material (6; 10), controlling said advancing by acting on a further region of said sheet material (6, 10) disposed upstream said region; said advancing and said controlling take place by using electronic auxiliary means; a container comprises first and second wall means connected to each other along a peripheral sealing (130) in order to define an internal space (132) and regions (104, 110) positioned in a pre-established manner on faces (106, 112) of said wall means.

1. Apparatus, comprising forming means for joining first sheet material and second sheet material together, first clamp means downstream of the forming means for indexing the first sheet material and the second sheet material after being joined together by said forming means, second clamp means upstream of the forming means for indexing said first sheet material toward said first clamp means substantially synchronously with said first clamp means, characterized in that, third clamp means are provided upstream of said forming means for indexing said second sheet material toward said first clamp means substantially synchronously with said first clamp means.2. Apparatus according to claim 1, wherein said first clamp means and/or said second clamp means and/or said third clamp means is coupled to non-mechanical control means.3. Apparatus according to claim 2, wherein said non-mechanical control means comprises electronic control means.4. Apparatus according to claim 1, 2 or 3, wherein said first clamp means and/or said second clamp means and/or said third clamp means is/are coupled to a respective electric motor by position control means.5. Apparatus according to claim 4, wherein said position control means comprises screw means engaged into respective lead nut means to which support means of respective grasping means is coupled.6. Apparatus according to claim 1 and further comprising fixed grasping means disposed upstream of said further clamp means.7. Apparatus according to claim 6, wherein said first clamp means and/or said second clamp means and/or said third clamp means is coupled to non-mechanical control means.8. Apparatus according to claim 7, wherein said non-mechanical control means comprises electronic control means.9. Apparatus according to claim 6, 7 or 8, wherein said first clamp means and/or said second clamp means and/or said third clamp means is/are coupled to a respective electric motor by position control means.10. Apparatus according to claim 9, wherein said position control means comprises screw means engaged into respective lead nut means to which support means of respective grasping means is coupled.
