Claim 0:
1. A winding condition generating apparatus comprising at least one processor configured to:
calculate a winding condition of a new wound web from a winding parameter of the new wound web, using a learning model created by machine learning with a combination of a winding parameter and a winding condition in producing a wound web that satisfies a target winding quality as training data; and
output the winding condition,
wherein the winding parameter includes a web width, a web transport velocity, and a web winding length,
wherein the winding condition includes a tension of the web at the start of winding and a tension of the web at the end of winding, and
wherein in a case where with respect to a set of the winding conditions obtained in producing the web, which is the training data, a value of each winding condition item is denoted by Cni, an allowable quality range value set to the value Cni of the winding condition item is denoted by Tni and the number of items to which the allowable quality range value Tni is set is denoted by N, a range obtained by the following Equation for each item is added to the winding conditions, and 3N−1 pieces of the training data or a part of the training data is assigned as additional training data,

Ck=Cni±0.5×Tni.
