Material placement system

An apparatus comprising:

• a roller having an axis of rotation configured to move over a curved path, between a first position and a second position relative to a material delivery structure in which the roller is in the first position when a plurality of lengths of material is placed on a surface of a mold when the material delivery structure is moved in a first direction and the roller is in the second position when the plurality of lengths of material is placed on the surface of the mold when the material delivery structure is moved in a second direction that is substantially opposite to the first direction;
• a first guide on a first side of the material delivery structure in which the first guide is configured to guide a first number of lengths of material in the plurality of lengths of material to the roller;
• a second guide on a second side of the material delivery structure in which the second guide is configured to guide a second number of lengths of material in the plurality of lengths of material to the roller in which the first guide comprises a first number of channels and the second guide comprises a second number of channels;
• in which the first number of channels is offset from the second number of channels;
• in which the first guide is positioned at an angle relative to the second guide such that the first guide and the second guide substantially intersect at a location of the roller;
• and in which the roller, the material delivery structure, the first guide, and the second guide form an end effector;
• a supply configured to send the plurality of lengths of material to the material delivery structure;
• a positioning system associated with the material delivery structure and configured to move the end effector relative to the mold configured to receive the plurality of lengths of material;
• a material movement system configured to move the first number of lengths of material in the plurality of lengths of material towards the roller and move the second number of lengths of material towards the roller;
• a cutting system associated with the material delivery structure and configured to cut at least one of the first number of lengths of material in the plurality of lengths of material and the second number of lengths of material in the plurality of lengths of material;
• and
• a clamping system associated with the material delivery structure and configured to substantially halt movement of the at least one of the first number of lengths of material in the plurality of lengths of material towards the roller and the second number of lengths of material towards the roller.
