OK...creation of a new model works, but there was also a problem in my 
foreach-loop which results in max_execution_time exceeded.

I have created a little method to create a copy of my models:

/**
  * make a copy of a domain model object
  *
  * @param Tx_Extbase_DomainObject_DomainObjectInterface $object The 
object to copy
  * @return Tx_Extbase_DomainObject_DomainObjectInterface The copied object
  */
public function 
makeCopyOfModelObject(Tx_Extbase_DomainObject_DomainObjectInterface 
$object) {
	// the object must be an instance of DomainModels
	if(!$object instanceof Tx_Extbase_DomainObject_AbstractEntity) return 
$object;

	// get type of model
	$type = get_class($object);

	// create an empty model class
	$model = $this->objectManager->get($type);

	// get an array with all getable properties and their values
	$properties = 
Tx_Extbase_Reflection_ObjectAccess::getGettableProperties($object);

	// set the retrieved values to our new model
	// TODO: Maybe someone has a better possibility how to copy objects 
into another object
	foreach($properties as $property => $value) {
		if(Tx_Extbase_Reflection_ObjectAccess::isPropertySettable($model, 
$property)) {
			Tx_Extbase_Reflection_ObjectAccess::setProperty($model, $property, 
$value);
		}
	}

	return $model;
}
