Pressing apparatus and pressing and depositing system for depositing a sliver on a double-curved surface, and use and method

A pressing and depositing system for depositing a sliver on a surface, with the system comprising:

• a pressing apparatus for depositing the sliver on the surface, the pressing apparatus comprising:
• a first segment comprising a first rolling element and configured to roll along the surface;
• a second segment comprising a second rolling element and configured to roll along the surface;
• an assembly frame configured to hold the first segment and the second segment and comprising an opening in a radial direction;
• a suspension apparatus that is configured to:
• attach the first segment to the assembly frame;
• and
• rotatably mount the first rolling element on the assembly frame the suspension apparatus comprising:
• a spring assembly configured such that a relative movement between the first rolling element and the second rolling element is realized in the radial direction of the first rolling element due to an action by the spring assembly, the spring assembly comprising:
• a spring accommodated in a hollow space;
• and
• a sleeve configured to form the hollow space with the opening and the sleeve at least partially accommodated in the opening and guided by the opening in the radial direction;
• and
• a robot comprising a robotic arm, the robotic arm configured to:
• receive the pressing apparatus;
• and
• move the pressing apparatus along the surface.

A method for depositing a sliver on a surface, comprising:

• attaching a first segment with a first rolling element to an assembly frame;
• attaching a second segment with a second rolling element to the assembly frame;
• attaching a spring assembly to the first segment and the assembly frame in such a way that a relative movement between the first rolling element and the second rolling element can be realized in a radial direction of the first rolling element by an action of the spring assembly;
• accommodating a spring of the spring assembly in a hollow space formed by a sleeve and an opening,
• wherein a suspension apparatus comprises the sleeve in the radial direction and wherein the sleeve is at least partially accommodated in the opening and guided by the opening in the radial direction;
• rotatably mounting the first rolling element and the second rolling element on the assembly frame;
• moving the first rolling element in a direction along the surface;
• and
• carrying out the relative movement between the first rolling element and the second rolling element in the radial direction of the first rolling element.
