Comparison of binding materials and tools

Up to now binding was carried out manually. For this reason the wine grower has an interest in the materials and tools wich will allow him to carry out the bindings in the fastest and cheapest manner. The following article deals with the corresponding worktime studies and cost comparisons.

Binding still has to be done manually. This is why the wine-grower is interested in the materials and tools with which he can do the binding in the fastest and cheapest manner. The following article deals with the corresponding work-time studies and cost comparisons.

The various binding materials are distinguished in terms of material, e.g. plastic, metal or natural products (wicker, hemp) and in terms of durability (useable once or over a number of years). Binding material which can only be used once includes wicker, binding wire (vine-binding yarn) and wire with plastic sheathing. Binding wire is probably the most widely used material. It is cheap, fast and easy to manage and can be simply cut and removed on pruning. Wicker is still used in some regions. Often the wine growers have their own willows which they cut themselves. Frequently this is done by the "grandfather" so that no additional costs are incurred. An advantage of wicker is that it decoposes into the ground.

Binding tools: minimum amount of effort

Binding tools work with one-off binding materials for binding of shoots and in some cases for the binding of trunks. In practice, drill tools, the Ligapal tool, binding pliers, the Beli binding tool and the Max Tapener tool are used. Binding tools allow rapid binding with little effort. The binding material is generally very cheap but it is well worth comparing the costs per binding before purchasing a tool.

Comparison of working time and costs

Tables 1 -2 give a working time and costs comparison for bindings of shoots with various materials and binding tools.
Tables 1 and 2 show that the Beli binding tool is the best in terms of prices and performance. The purchase costs of the individual tools are not taken into account in the calculations.
The price differences for the binding tools and the binding materials are based on different supply sources and different purchase quantities. Altough the binding pliers is just as fast as the Beli binding tool, the high material costs of almost 0,5 Cent/binding mean that it performs poorly in the economic comparsion.



Conclusion; In the comparison of various materials and tools for the binding of shoots, the Beli binding tool proved to be fast and cheap. For trunk binding the Max Tapener tool achieved the best results in terms of price/performance ratio..
