Improved gripper-type chain attachments for thermoforming
Tsubaki is launching a new range of 'gripper' chains to be used for thermoforming in various sectors including food, electrical and medical packaging. Whereas conventional gripping attachments often open vertically, Tsubaki's open to the side as well, providing a larger opening, preventing jams and making loading easier. This new range is available with many variations of transmission chain, including Tsubaki's Lambda lube-free chain. Offering extended chain life and minimal maintenance, Tsubaki's gripper chain provides a new option for thermoforming.
Tsubaki, a leading manufacturer of drive and attachment chains, is developing the new advanced design of gripper chain for form, fill and vacuum sealing wrapping applications. According to the company, other attachment designs have inherent problems, such as being prone to breakages or not gripping the film correctly. However, Tsubaki's attachments are claimed to offer excellent wear characteristics and a design that 'cams' open to create a far wider aperture that prevents jamming and unsuccessful loading.
Incorporating a coil spring wound from square-section wire, the gripper surface area and spring are larger and so less prone to breakage. Furthermore, Tsubaki says that other attachment types do not always grip the film properly, as the gripping attachment will only open and close vertically, creating a narrow opening. Tsubaki's 'gripper' mechanism opens vertically then sideways, improving the engagement of the film and reducing the possibility of jamming.
Range options
A range of options ensures that almost any customer need can be met. Tsubaki holds the two most common chain sizes in stock, although almost any size is available through the made-to-order option. The chains are produced with a hard-wearing and protective nickel-plated finish as standard, suitable for general use in temperatures ranging from -10degC to 150degC.
Other options are available, including stainless steel chains for applications that will be subjected to aggressive wash downs or where acidic products are in use. Tsubaki can also supply the gripper attachment within a Lambda chain. This is a self-lubricating chain that reduces maintenance needs and is suitable for use where the risk of product contamination or marking by external lubricant is an issue.
The chains can be used in a range of applications from food packaging to the packaging of medical supplies. Tsubaki believes it is important to recognise each client's individual requirements and to understand fully their needs in order to provide a suitable product, offering different chain types and lubrication options, including USDA H1-approved food grade lubrication. Within these industries, Tsubaki hopes to establish the advantages offered by this improved design and product specification.
All Tsubaki products have short lead times when available from stock or built to order from stocked components. Contact Tsubaki for more information, product literature and support material.
